pyromanic Posted March 2, 2005 Share Posted March 2, 2005 Ok, I'm scrapping an 86 GL, EA 82 and parting it out to the 85 tranny swap job. But my point is this, that 86 engine was surely high miles. Leaked oil every where it could. Ticked like crazy. And since the 5 sp MT was just about shot, and it had considerable body damage, I decided it was over. So maybe I heard the TOD. Probably? Now moving on to the 85, I just swaped in a junk yard 5 sp DR. Nice quiet Trans. This EA 82 just had 1800 bucks worth of rebuild. No leaks. Runs smooth. And is quiet untill it warms up. Then it clatters. Not tick, like the other one, but clatters. To me it sounds like the valve train, all clattering equally loud. What is this? Problem is, I don't really know what a healthy EA 82 is supposed to sound like. Maybe this is normal. I'd like it better if it was as quiet all the time as it is during the first five minutes, untill it gets warm. I ignorantly await ejecaten. Thanks.

85Sub4WD Posted March 2, 2005 Share Posted March 2, 2005 My bet is it has a really light oil in it - like 0w or 5w something and it is thick enough at startup to prevent the clatter, then when it warms up, the oil thins, and the pressure drops If you have the correct oil then ... oil pump reseal Link to comment Share on other sites More sharing options...
pyromanic Posted March 2, 2005 Author Share Posted March 2, 2005 Well, I already changed the oil to 15 w 40. It's still cold here in central oregon. Is that too light? But my super mechanic buddy (but not with soobs) says that his theory is this: Since the car sat for five years, the hydrolic lifter are stuck, and not pumping up. He suggested that they will pump up in time with use. Or, he said, try this: drain one quart of oil, then back fill with one quart of diesel. Run for for minutes, no longer. One reason his theory does not make sense to me, is why would it be so quiet when it's cold. Sounds like the lifters are pumping up to me. I don't know. Sounds dangerous to me. Is he even on the right track regarding stuck lifters when a car has sat for years? All thoughts appreciated. Pyro Link to comment Share on other sites More sharing options...
85Sub4WD Posted March 2, 2005 Share Posted March 2, 2005 Would not doubt stuck lifters DO NOT PUT DIESEL IN YOUR CRANKCASE - it is not that clean and there is a VERY good chance it will explode use a quart of MMO or equiv to do the proceedure I think that an oil pump reseal is your best bet - make sure you don't have a leak Sorry - MMO = Marvel Mystery Oil Link to comment Share on other sites More sharing options...

There are no leaks. Should also be new oil pump and seal, as engine has only 12000 mile on rebuild before it sat for five years. If lifters are stuck, why is the engine quiet when cold?

85Sub4WD Posted March 2, 2005 Share Posted March 2, 2005 OK - I think the lifters are stuck - quiet when cold b/c they were stuck in the proper position for when the engine is cold? I dunno - Marvel Mystery Oil (MMO) and reving 4,500-5,000 rpms should fix the problem - otherwise, daily driving will Good Luck! Link to comment Share on other sites More sharing options...
pyromanic Posted March 2, 2005 Author Share Posted March 2, 2005 Oh duh, MMO. I have a gallon of marvel on hand. Just didn't put the initials together in my head. Tired I guess. by the way, diesel is not explosive at all. Which is why when used as fuel in internal combustion engins, it must be compressed. Now I won't dispute that it's not all that clean. But check this out. Most of the comercially made crankcase additives which are disighned and advertised to clean engines and free stuck lifter and help with gumed up valves consist of ingredients of diesel like and kerosene like stuff. No kidding. Or not. Just what I have heard all my life over and over. (I'm 50) Might not be true though. But since I have the Marvel, I'll try it. Thanks for all the input guys.

TheSubaruJunkie Posted March 2, 2005 Share Posted March 2, 2005 MMO solved my valve clacking. Ive never heard of valve tap ending the life of an engine, but after a while I feel like ending my life. The noise drives me absolutly insane, and im sure im not the only one. Once the legacy got it real bad. An oil change with 10w30 didnt do it, so i added a quart of MMO and took the car for a drive. Had to get it up to about 7k on the tach in order for the tapping to stop. When I had the problem with the RX a bottle of MMO solved it (that and 2.5 quarts of oil) -Brian Link to comment Share on other sites More sharing options...
