Deener Posted April 28, 2011 Share Posted April 28, 2011 What about the oil pump seals? Shaft seal, O-ring and 'mickey mouse' shaped gasket/seal? Did you do those when you did the rebuild? Quote Link to comment Share on other sites More sharing options...

Did you do those when you did the rebuild? yeah, i replaced those. i dont know if the oil pressure is enough. it runs about 38 to 40 psi when fully warmed up. thats with a aftermarket guage hooked up to it.

GeneralDisorder Posted April 28, 2011 Share Posted April 28, 2011 Most of the time the only solution is new oil pump, lifters, and cam carrier seals. Rick Quote Link to comment Share on other sites More sharing options...
MilesFox Posted April 28, 2011 Share Posted April 28, 2011 may just need to replace the worn lifters. Now that you have replaced everything, the lifters may just be done in already. Replace any ones you can squeeze down byhand Quote Link to comment Share on other sites More sharing options...
ruparts Posted April 29, 2011 Share Posted April 29, 2011 (edited) hi, i have had a few do this, and it was found that debris in the cam carrier restrictor orifice was the problem. the cam case has a oil restrictor pressed into the supply hole, it is a brass plug with a small hole, but the bigger passage between the cam and the restrictor is a natural trap for stuff, old solicone is especially prone to catch , anything that can squish through a 1/4 in oil supply hole under 50-70 psi , but not through a pin hole can trap in there. it requires to take the cam case back off and slip the cam out , you have to blow out the passage through the restrictor from the head side, toward the cam bore. i bet you have some crud in there blocking the orifice.

RapidElastic Posted April 30, 2011 Share Posted April 30, 2011 Im hoping mine wont come back after im done with the oil pump :/ Quote Link to comment Share on other sites More sharing options...
idosubaru Posted May 1, 2011 Share Posted May 1, 2011 best sequence in my opinion and experience: 1 reseal the oil pump. it's easy and when mated with a timing belt job is hardly any work. 2 replace the oil pump with a new one. this has cured every ticking EA82/ER27 i've come across (with one exception below). you can skip step one if you don't mind the expense to begin with. 3 replace faulty HLA's. i've come across seized HLA's that wouldn't even compress in a vice. this was obvious because they were both associated with a particular cylinder on an XT6, the others on the same side were quiet so it obviously wasn't oil supply related. and of course gunk caught in the lines wouldn't be any good. i've seen a glob of RTV get stuck at the oil port in the bottom corner of the cam carrier where that metal reinforced oring goes.
