Phizinza Posted October 10, 2005 Share Posted October 10, 2005 The green text doesn't need to be read. After looking at the size of the thred I thought I might just try and save you time Hey, I just got my Brat back and working after fixing the oil leak thru the striped out exhust stud hole which I had already put a instert in (and it striped most of its thread out). So after using epoxy glue made for the job and putting the pipes back on with new gaskets. It all seemed to work. But now I want to fix some noise issues with my EA81. Now for the question It has always had a loud tappet noise. I thought after adjesting the tappets it would fix it. But no, its still tapping away. I read a bit about it all on this forum and found it might be the lifters? I'm not 100% sure on all the parts in a EA81, so please explain things easy for me So. The sound sounds like its comming from each head (the 2&4 side is a little louder) It sounds just like a tappet noise. Are these engines just loud like this? Does something wear and make this noise? I know it can't be harm full to the engine cos its been going for a long time with the noise. I just want my car to be better sounding. The 2" pipe makes it sound great, but tis ticking just makes it sound crap Is there a few things you can do to make a EA81 quite? Thanks for any help.

Ross Posted October 10, 2005 Share Posted October 10, 2005 If thats the original engine, it will have hydraulic lifters. Did you adjust them according to the hydraulic lifter procedure? If you adjusted them accoding to the solid lifter adjustment procedure, the will be wrong, and you should re-adjust asap. (i.e. if you used feeler gauges during adjustment, you did it the wrong way!)

Phizinza Posted October 10, 2005 Author Share Posted October 10, 2005 Is it obvius when there are are hydraulic lifters in the engine? It looked all soild too me, but its the onlt subie engine I've looked in. Is there a way I can find out easily if its a hydraulic lifter ea81? I done the tappets with feeler gauges like the manual told me. I'll have another look in the manual and see if theres a bit about the lifters in there.

TomRhere Posted October 10, 2005 Share Posted October 10, 2005 The '84's with Auto trans, all '85 and up have Hydraulic lifters. I did mine the wrong way when I swapped heads, took me a few tries to get it right, like 4. Here's the procedure, taken from the FSM. Someone posted this on here, and I saved it. Engine cold, 20-40*C/86-104*F Done in 2 steps.. Step 1; With engine @ TDC #1 cylinder (compression stroke) adjust the following; Intake & Exhaust on #1, Exhaust on #3, Intake on #4. Step 2; With engine @ TDC #2 cylinder (compression stroke) adjust the following; Intake & Exhaust on #2, Intake on #3, Exhaust on #4. Procedure; Remove Rocker covers. Bend the tab of the lock-washer and loosen the lock nut. Turn the adjuster screw in approximately 4 turns. Leave it sit for 15 minutes. (Don't rush this like I tried to do) Unscrew the adjuster screw SLOWLY until rocker just stops moving, this is the "Zero-Point". ( If you can get your fingers on the push-rod, it should just start to be able to spin between your fingers at this point) Turn adjuster screw out 1-1/2 turns more. Tighten lock nut and bend tab on lock-washer. (Be sure to hold adjuster screw while tightening the lock nut) Re-install Rocker covers. I ran my engine without the covers on, just to make sure I had them right. Took me 4 adjustments to finally get all of them quiet again. Running without the covers makes a nice mess on the garage floor, but won't hurt the engine any. Above all, don't rush the waiting period, it won't do you any good. 20 minutes would even be better, really. Link to comment Share on other sites More sharing options...

I'll have another look in the manual and see if theres a bit about the lifters in there. If it was a Haynes manual or similar, it wont say anything about hyd. lifters. Do the above procedure, unless you think its an older engine. You cant see the lifters, but there are a few ways to check if you are unsure: -Hyd lifter engines should have a "do not adjust" sticker on the rockers (may fall off though) -they will have a small boss on the left (looking from front of car) top side of the engine block where the knock sensor is located on turbo cars (it wont be drilled, just a small round boss). -you can also tell from the pushrods - they have different ends on them. Anyway, if its the original engine, do the procedure above. Link to comment Share on other sites More sharing options...
Phizinza Posted October 11, 2005 Author Share Posted October 11, 2005 As i said before. I'm not 100% sure on all the parts in a EA81, so please explain things easy for me. I included a picy of what I think you are talking about (this boss thing)... Is the red one or the blue one what you are on about? I dont have any stickers on the rocker covers (but I didn't replace on of the covers with one out of a older subie. My FSM has nothing on EA81 hydraulic lifters (its a Gregory's.) Is this what your on about? If not, tell me where it is exactly or give me a picture to go by. Also, is there somewhere that tells me if the engine is the original to the car? Like a engine number to VIN? Link to comment Share on other sites More sharing options...
Ross Posted October 11, 2005 Share Posted October 11, 2005 Nah, the boss is on the top of the engine. look behind the inlet manifold, on the left (looking from front) side of the engine, perhaps 50mm or so from bell housing (thats a guess from memory). It will be about 15mm in diameter, and raised perhaps 5mm. It wont have a hole or anything in it. Link to comment Share on other sites More sharing options...
Phizinza Posted October 11, 2005 Author Share Posted October 11, 2005 Nope. Nothing there. Its all just shaped around the dip stick. And I can't see anything like what your talking about there. So, that means its soild? So what does that mean, its just always gonna be loud? Time for some saving up, first I have to pay off my debt.......

nzdusty Posted October 12, 2005 Share Posted October 12, 2005 So does the procedure mentioned before work with EA82 engines with hydraulic lifters?? Link to comment Share on other sites More sharing options...
Ross Posted October 12, 2005 Share Posted October 12, 2005 I don't think the ea82 ones have adjustable tappets? Phizinza, i think perhaps you should check your push rods before you rule out it having hydraulic lifters. Can you take a pic of one? The ends are different. Also, did it have lock washers on the tappet adjusters? Link to comment Share on other sites More sharing options...
Phizinza Posted October 12, 2005 Author Share Posted October 12, 2005 No, there wasn't any lock washers. I really dont want to take the rocker covers off as it took me 5 goes with different types of gasket goo and silicone to put them on without leaking! But I guess I will just have to take them off and fix this problem, then try that sealing thing all over again :-\ ........... Maybe I should get some of those SUB4 all alloy rocker covers!

Ross Posted October 12, 2005 Share Posted October 12, 2005 Maybe I should get some of those SUB4 all alloy rocker covers! Maybe you should get some gaskets!! I've been re-using the gaskets on them for ages, no leaks. Perhaps yours are just too old/not there! Link to comment Share on other sites More sharing options...
Phizinza Posted October 12, 2005 Author Share Posted October 12, 2005 I went thru 4 new gaskets while stopping it from leaking. I know there must be something I was missing.... My dad has always worked on his own cars and has rebuild two motors that I know of, and he watched me try and fix it twice, he has just as much idea about what wasn't going right as I did!. Hrmm.. I just found out that the insert I put in the exhuast stud hole (after it got striped out) (and now the insert has striped out the new thred) that the high temp epoxy glue I used didn't hole and the insert is just lose in there. I don't think the engine is going to be running for awhile now... it just keeps getting worse! Oh well. gotta figure out how to bolt the exhust on now. Maybe tech screws? that always seem to fix leaks in our roof! Link to comment Share on other sites More sharing options...
Ross Posted October 12, 2005 Share Posted October 12, 2005 Is there enough material left in the head to use a helicoil? On the gaskets, make sure everything is clean and dont overtighten the bolts and it should be sweet...... If the bolts have been overtightened in the past, the covers may be bent? It sounds like you may have solids. Check the push rods, although just because it has pushrods for hyd.s doesn't necissarily mean it still has the hyd.s (someone had replaced them with solids on my ea81t, and left the original push rods, causing me much confusion!). One thing that you could try: -Take rocker cover off. -Slacken a tappet so that there is clearence between rocker and valve. -Leave for 15mins -adjust the tappet so that the clearence is just taken out. -further tighten tappet, say 4 turns -leave for 15-20mins. -loosen tappet again, taking note of how many turns it takes till it goes slack. If there is a difference between the 4 initial turns and the number of turns it takes to back it out, you have hyd. lifters. If its exactly 4 turns to back it out again, you have solids. Doesn't that sound fun to you? Link to comment Share on other sites More sharing options...
Phizinza Posted October 12, 2005 Author Share Posted October 12, 2005 the inserts are like heilcoils (only cheap) I decided I'm taking the engine out and getting the head welded up (should work much better.) When I do all this I will have a look at the rods and take some pics. My dad's turned up and he seems keen on getting the engine out now. So maybe tonight I'll have the pics. Till then, ARGHHHHHHHH!

Phizinza Posted October 12, 2005 Author Share Posted October 12, 2005 Heres some pics. Engines out, heads off getting welded (the proper way to fix it!) And this is what the rods and lifters looks like (with out the block opened up, not going that far) Thats what you can see of the lifter when you look inside the block from where the head fits. All four of the pushrods have this type of end on both ends. All four of the rods! Can you tell me if I have soild lifters now? Thanks for all the help and time Ross!

Ross Posted October 12, 2005 Share Posted October 12, 2005 Those rods are for the solid lifters. So you should be able to adjust them using the normal method with feeler gauges. Interestingly enough, that means your engine is pre-'85. Link to comment Share on other sites More sharing options...
Phizinza Posted October 13, 2005 Author Share Posted October 13, 2005 Yeah... the engine in there has had work done on it, the guy who had it last got twin carbs, and also he said he got bigger valves and a worked cam (I think thats all BS though...) I am going to messure the the valves and if there the same as a normal EA81, I would say every thing else is, but the carbs. So anyhow. I think I will just get the EA81 working good again and then spend some money on a motorbike I have to get it running for some fun (was just watching my old vidoes of on the bike and i now remember how fun it was. So I want to do it again of cause! And the car can just stay as a pig to drive... One day I will fit a EJ in a offroad subie... one day! New project, to fit a 250cc four stroke into a Suzuki DS80 (80cc) chassie! Muhahaha Link to comment Share on other sites More sharing options...
