To be clear, the front of the motor has the timing belt and faces the passenger side. The REAR of the motor also has cam seals, distributor, and cam shaft sensor and faces the drivers side of the car.

I thought you were here to get help and you seem to have a handle on it. Have a good night.

 

I do not know what you would call the side facing the firewall, the left side? I am stumped, I can not figure out the leak, although it appears that the likely sources have been ruled out. Tomorrow I will stare it down further, and pour more oil into the motor to try and pinpoint it, thanks for the help so far.

 

Yeah......
I dont know where you got that from, but there is no such motor EVER in an 850.. All 850 motors start with B52...

In 95 there were only 4 motors with 3 fuel system options.. 2 motors only available in the US and only 1 fuel system available in the US Motronic 4.3... the motors only came in a 2.3L (turbo) or a 2.4L ( N/A)
Around the world there was a 10 valve 2.0L motor and a TDI


And as far as I can tell B3440 is not even a volvo motor.. Its a chevy avalanche motor

 

That number is molded into the valve cover.

 

It is the exhaust cam seal. It was actually pushed out, so I pushed it back in, no leak. I will order new seals and replace both, then plan on tearing down the PVC system. Thanks for all your help!

 

Do the PCV at the same time.. otherwise youll just end up popping out the seals again or even worse you could pop a RMS

 

That is the plan, all at once.

 

That's what she said.

 

Yes, that is what I noticed this morning. I reseated it, and the leak stopped. I hope it will hold until next weekend when I have the parts (and the time) to replace it and clean the PVC system.

 

I tore down the intake manifold (cleaned the TB and manifold while it was off) and cleaned/replaced the PCV system and all lines today, no problems other than with the 2 lower bolts on the manifold. Extension city on them!There is nothing sweeter than putting it back together and it cranks strong on the first pull.

Tomorrow I will do the cam seals.

Thank you to the forum and all the guys who post here, it really made it easy.

 

I would hold off on the cam seals to see if they start leaking again. Doing the PCV may have relieved enough pressure to stop them from popping out.

 

I have them already, but that is a good point, maybe I will just pull the covers, check them to make sure they are seated then wait.

 

I went ahead and pulled the cam covers to check the seals, they are both in place, so I will follow your advice and leave them be for now. It runs good, no more leaks. Thanks again.

 

No joy, still bleeding from the seals. I'll do it next weekend.

 

Cool. If the belt is wet, I would go ahead and replace it as well. Do you know the history of the belt, rollers, and tensioner? I seen some instructions where a guy actually secured the belt to the other cam sprocket and roller, pulled a cam off and replaced the seal and put the cam back on.

 

Well, I pulled and replaced the seals, marking everything thoroughly, put it back together and now it won't start. Turns over fine, but no fire.

 

Yes, I did both sides on the front. The alignment marks are all perfect, were is the cam position sensor?

 

Did you do both sides?
Sounds like either your cam position sensor or timing is off

 

The cps is under the upper torque mount, rear exhaust position.

 

I checked for spark and fuel, both are OK.
