Excess oil in Heads

Hello, After 3 months dealing with my oil pressure problem, now Im having 50 of oil pressure in idle when the car is cold and 20-25 idle when the car is in 175 degrees.

Now im having another problem: I have excess of oil in my heads, they are getting full of oil, specially the co-pilot side, in this side the oil is leaking from the breather. I install new Baffles, and I stop the leaking in the valve covers, but now im having problem with my breather. If I take out the breather I can see the oil coming out with pressure, so I dont know what is happening now.

I install a new High volume High pressure oil pump, I install new push rods (that I bought from mondello) and they supposed to be restricted, but Im not really sure, im going to check on that. To help draining the Heads I drill on each head a 1/2 inch hole, then I drill another 2 holes in the block, and connect the heads with the block with 2 hoses to help draining the oil.

I have more leaking problems when the car is cold. Im using now 15w 40 oil because my clearances are too tight, but Im not sure is changing to 20w 50 will help my leaking problem?

my Heads are B code.

What else I can do, or what else I need to check to solve this problem?? is that common on olds cars?

thanks for the help again guys

Alex

This is even funnier than the one about measuring heater hoses with vernier calipers.

Looks like I have another new sig line.

Look *** if you can't make a positive contribution why don't you just stay off the keyboard and go take your meds.

Obviously you've never seen crankcase pressures become great enough from blow-by to blow oil right out of the oil filler and if it will do that it will certainly be great enough to prevent oil from flowing back to the sump at least until there is no more oil to pump out and the darn engine seizes up.

Aside from that idiot, no one said measure the darn hose only the hose nipples on a year model having several sizes possible.

The valve covers look like maybe cheap aftermarket covers. There needs to be a baffle under where the breathers go and still they must be installed correctly and designed correctly. I would not assume right away that there is a serious engine problem untill research is done. I would assume that oil is being directed thru the baffle and out of the breather by some oddity. I would not assume that the area under the valve cover is being completely filled with oil and is being forced out of the breather......No this is not a common problem with old cars....

So have I.

But the OP did not say anything about a dipstick or a breather.

I need guys like you on my speed dial.
But he did say with pressure. I guess we need to define it being oil or blowby.

Take the cover off the co-pilot side, then run the engine and tell us where the oil is coming from.

I hope this is more helpful than the second post.

It's a shame a guy can get belittled just trying to help out.

Maybe we need to hand out *** of the day awards. I know where I'd cast my vote.

"Helping out" does not include making a diagnosis without knowing the symptoms.

If you would like to discuss it further, send me a PM.

I have no interest in sending you a PM or recieving one from you.

I'm only here to learn a few things and maybe help a guy when my limited knowlege allows. If I am wrong I expect to be politley rebuked, is that too much to ask?. In the last 30 + years of working on cars I did manage to learn a few things.
There is a slight chance I may know something you don't.

I had the same problem but I do not think my problem is the same as the OPs. I once bought a car that sat for many years and there was much sludge in the engine especially in the oil return passages in the heads. One bank was really bad as I pulled the valve cover off after shutting down the engine and about a quart of oil leaked out all over the exhaust manifold........the front cross member.....steering linkage........garage floor....a real mess.

Not likely, as his is a fresh rebuild.
