Hello
I recently (July 2023) took off the oil pan to reseal it.
2 weeks ago I changed oil and it started the engine noise. I found a couple pieces of the gasket material in the filter reservoir and so I took it to the shop for a diagnosis.
They checked oil pressure and the top end pressure is significantly less then the low end.
The clean out for the oil passage to the top end is under the intake
it's got 244000 MI.
So they say I should replace the engine
Just looking for suggestions
It ran great until I put the new oil in.
Sincerely, baffled

 

to the forums!

There's more than 1 place to check oil pressure. I remember a discussion, I'll try to find it. You don't necessarily have an oil pressure problem, but with valve noise, better to be cautious.

But there aren't technically lifters.

 

Ok, I found it!

You must have used too much RTV or the wrong kind. Now there are bits of it floating around looking for places to lodge. You might be lucky and have most stuck in the pickup tube.
I am sure the shop is saying "replace it" based on the miles not anything else. However, it might be cheaper to just put a low mileage used engine in it. It is your wallet.

 

Sounds like you might not have placed sealant on the surface of the oil pan where the oil pump sump is


The oval at the pickup tube

Here is a closer picture

Just a 2 mm bead of sealant is all that’s required

 

thank you, I'll check
it

 

So I took the valve cover off and found two rockers laying on the bottom of the reservoir, anybody have a name of someone who can rebuild? I'm in shawnee, ks 66227.
thanks in advance

 

Doesn’t take much to remove the timing chain and then the camshaft and put the valve arms back in then replace the timing chain.

 

Holy cow, they had that valve cover off to do your timing chains. How could they miss it? Pretty rare for rockers to just fall off. Pics?

 

And no mention of a dead miss in the 1st post. If the 2 rocker arms were “laying on the bottom of the reservoir “ then it was running on 3 cylinders or maybe as few as 2.
Damage done. Time for another engine.
