fshnidiot Posted March 19, 2011 Share Posted March 19, 2011 (edited) I just dropped a resealed EA81 I bought into my 82 Brat. Fired right up but I have no oil pressure and valves ticking bad. I rebuilt and dropped in another oil pump (I checked it and it's within the specs in my book for wear. both pumps are still good) and adjusted the valves with no change in pressure or noise. No leaks anywhere, temp stays cool, sounds and feels really good and strong except for the ticking. With the motor running i removed the oil filler cap and I have enough air coming out of it to use it as a blow dryer. Air is also blowing out the valve cover breather tubes like crazy.(forced air induction for my weber ) Am I right in thinking there is no oil pickup tube going from the block into the oilpan and as a result I'm just sucking air? It's full of fresh oil so I know that's not the problem. Thanks, Frank Edited March 19, 2011 by fshnidiot Link to comment Share on other sites More sharing options...
987687 Posted March 19, 2011 Share Posted March 19, 2011 Is there any evidence it's been pumping oil? Easiest way would be to pull the oil filter. If no oil comes dripping out, it isn't pumping. If you're run it much with no oil circulation you've probably fubared the bearings... good luck. Link to comment Share on other sites More sharing options...
fshnidiot Posted March 19, 2011 Author Share Posted March 19, 2011 I'll go pull the filter right now and check. It hasn't been run much (5-10 miles at 35mph or less back and forth to the parts store) so hopefully I haven't hurt it yet. Back in a few.

WJM Posted March 19, 2011 Share Posted March 19, 2011 If you went that far and the engine didnt lock up, I'd say something is wrong with your oil pressure indication system. Link to comment Share on other sites More sharing options...
fshnidiot Posted March 19, 2011 Author Share Posted March 19, 2011 There's oil in the filter and some dripping out of the pump. No evidence of any oil antifreeze mixing, no bubbles in the radiator etc. The pressure guage needle comes up about 1/2 way to the 0 mark on the guage for a minute or so after startup and then drops to the stop peg as it warms up. Then I get the blow dryer effect. Frank Link to comment Share on other sites More sharing options...
fshnidiot Posted March 19, 2011 Author Share Posted March 19, 2011 New sending unit and I replaced the wiring with about 18-24" of old wiring replaced from where the harness splits behind the intake manifold. Link to comment Share on other sites More sharing options...
naru Posted March 19, 2011 Share Posted March 19, 2011 With the motor running i removed the oil filler cap and I have enough air coming out of it to use it as a blow dryer. Air is also blowing out the valve cover breather tubes like crazy Hydraulic lifters? That much blowby will overwhelm the PCV system,pressurize the crankcase and impair oil flow.Sorta like trying to blow up a tire with lung power. IME,oil pump specs only confirm bad ones not good ones. I`ve had ones that meet specs,but,were crap. Sounds like your gauge has a problem. I would try a mechanical gauge for confirmation. Ticking might be a sticky valve. Regardless of oil pressure,that much blowby indicates a serious engine problem.Consider a compression and/or leakdown test.

fshnidiot Posted March 19, 2011 Author Share Posted March 19, 2011 Non hydro motor. Oil pickup was there so that wasn't it. I dropped the pan and found some chunks in the bottom. 1 piece looks like JB weld or something that was molded into a hole so I'm gonna guess that it's dead:horse: and start the search for a good cheap short block to drop my manifold and weber on. Again. Thanks for the help, Frank Link to comment Share on other sites More sharing options...
DR DLEX Posted March 20, 2011 Share Posted March 20, 2011 one thing to check is the oil pick-up o-ring I have had one distort(melt) enough to loose oil pressure after warm-up... it was the last thing I checked after I swapped 2 oil pumps with the same results Link to comment Share on other sites More sharing options...
fshnidiot Posted March 20, 2011 Author Share Posted March 20, 2011 O-ring? What O-ring? There wasn't anything there. I'm gonna drop 1 in and see what happens and hope for the best. Thanks for the tip. Frank Link to comment Share on other sites More sharing options...
fshnidiot Posted March 20, 2011 Author Share Posted March 20, 2011 Well, atleast it reads at 0 oil pressure now so I'm guessing the gauge isn't working properly, and it still ticks, but it sounds quieter and wet, instead of dry and loud. Drive it till it blows time since I've already hurt it. Thanks for all the help! Frank Link to comment Share on other sites More sharing options...
WJM Posted March 20, 2011 Share Posted March 20, 2011 install an aftermarket gauge and sending unit. Link to comment Share on other sites More sharing options...

Frank don't kill the goose before dinner. check the valve covers for fresh oil...oil on each side=good ...oil on one side =bad ...very little or none=very bad--pull it hopefully you have good wet valve covers. in that case add a pint of 90w oil and drive the hell out of it have fun Link to comment Share on other sites More sharing options...
