1991 Saab 900 Classic Non-Turbo
2.1 L Engine
Completed on 12/16/09
is my story:
"Mine is a 1991 c900 16V, non-turbo that I picked up for free from a guy who gave up working
on it when he could not get oil pressure from his motor- he could not get any oil to pump out of the oil housing or pressure
relief valve. He thought it was oil pump that had gone wrong. I just thought the pump needed to be primed. So I did just that
and got oil to spew out of the oil housing and the check oil light to disappear after installation. But the valve noise
(severe knocking and tapping) under the cam over persisted. I just thought it was just bad lifters and gave the engine oil
treatments (with Seafoam, various detergent, etc.) and happily drove the car for a month.
Then it occur to me
last night that I ought to check to see if there was any oil going to the camshaft at all. Not surprisingly, the whole area
under the camshaft was dry. No sign of oil. I cranked the engine with the cover off to see if there was any oil spewing
out - none. I tried to see if bleeding the oil passage by unscrewing the 5 the black bolt, but there was absolutely no oil.
I have been driving like this for a month! I could see metal power around several tappets from grounding due to no lubrication."
Naturally, the only thing left to do was to swap out the engine. I found
a good used engine at a local dismantler for $350. It came with a 100-day warranty. They were a good source for replacing
all the parts that I broke while I was taking the engine out. I will not mention what they were. It's embarrasing. Anyhoo,
the swap is complete and I finally know how Saab engine sounds like.
My cherry picker - a post-thanksgiving find
for 100 bucks which I sold for 100 bucks on Craiglist after completing the project.
My Star Helper...
Tore out the inner joint where the CV axle mates up that
warranted another trip to the dismantler
Special Saab tool inserted to keep those fingers
compressed - they have to be compressed in order for the slave cylinder and clutch assembly to fit between the flywheel and
the tp of the gear box
A homemade pressure bleeder - all you need is a
bike inner tube, a hose clamp, and a tire pump.
