Dead timing belt .....

[Ho0ked]

So my 96 Gst died on the way to work some weeks ago.
The timing belt wasn't moving while cranking the motor.
My car has been leaking about 1 quart a week for a few months now, thought it was cam or crank seals.
This is what I discovered today,


1) timing cover had no gasket on it.
2) oil caked inside bottom of timing cover.
3) Timing belt missing bout 15 teeth between the crank spocket and the oil sprocket.
4) oil filter housing/oil pan my be to blame, they are wet often.

So the missing gasket is bad, but would it allow oil filter housing leaks to flow up into the bottom of the timing cover with the crank pulley spinning like mad ? or for that matter the oil pan ?

Im at a loss now I was expecting to see a shity leaking crank seal.......

Still have to pull the timing set and then the head and have C&C check the head out for damage /sigh

Anyone had anything like this happen ?

Thanks for any input guys

What did it sound like when the car died? I'm sure it made some noise because of the 15 teeth missing. Valves had to have a party in the cylinders. My guess is if you had that much oil in the timing cover it soaked the timing belt and evuentally caused it to fail. Timing belts are not fans of oil on them.

Ya I know the oil is the culprit.
The engine didnt make any noise when it died it was at low load barely above idle it just puttered out.
Will have the head off this week to see how bad the valves are, wish me luck

Now if only I knew where the oil came from or how it got on my T-belt

Any new news on this issue? Figure out where the oil came from and is there much damage to the head?

Sorry for the delay holiday and work and all that crap....

Anyway heads off, went to the machine shop locally.

1) 6 bent exhaust valves
2) oil leak still not determined......
3) $1200 in parts ordered today.....

Going to replace all the valves with stock and the valve seals
complete slowboy timing set
new lower timing cover
cometic HG
ARP's
complete upper gasket set
front gasket set (to redo the oil filter housing)
motor mount set
3" down pipe
3" high flow cat
balance shaft eliminator kit

also owe the machine shop $500 roughly.

Still need to save up for the 3" intake and Maf-t.....

After its all in ill pull the bottom cross brace and drop the oil pan and do its gasket also.....

thats it for now, waiting about 2 weeks for the parts to arrive......

Well that sucks, but hey sounds like you are upgrading some. Should be solid when you get done with it. Good luck.

Thee oil leak could have been coming from your auto tensioner if the bolts Are not tightend oil will come out of thoes holes. Other than that check your Rearmain Seal..

Hope it helps

a quart a week is pretty excessive. No valve cover seal will leak oil everywhere. Have you checked your oil pump to see if it turns freely? It takes almost no time to seize up the oil pump if it isn't getting oil.
