Oil Leak Issues?
Just a quick question.. I just picked up a 74 4 speed car and have noticed a few small drips on the grage floor that look like they are coming from different area's. Are there any "problem" area's on these cars that are known for leaking?
I haven't had a chance to crawl under and really take a look, but knowing in advance if something (pcv, valve covers, rear main, etc) was known for being a problem area would speed things up greatly.

Could be as simple as the pan plug (I think that 50% of cars leak from the drain plug a little to a lot) or a valve cover gasket or could also be a rear main seal or pan gasket and if minor leak, may not be worth fixing till you have to go there.

Hopefully its just a valve cover. Doesnt seem to be bad enough yet to justify replacing the main seal.. Glad to know that its common to leak from the plug, that's the type info I was looking for.
Thanks guys.

Likely areas:
Valve covers (check at rear of each cover too); rear main seal; oil pan; front main seal; timing chain cover; oil pressure gauge line and/or fitting in manifold; oil filter seal. That's about it, I think....

If you find front or rear main seal leak, I can recommend that you try a product made by ATP called AT205. Its a oil additive that I have seen work well a lot of times. Some times it slows it, some times it stops it all together. Worth a try to keep your garage floor clean. Work in trans and P/S also, seals only, not gaskets

AT-205 RE-SEAL™ is a special plasticizer which softens and expands hydraulic seals to stop leaks. AT-205 can be used for power steering, transmission, engine, differential and any hydraulic system (except brakes) - including jacks, lifts, plows, industrial equipment leaks. In addition, AT-205 will restore sunroof seals, wiper blades and any rubber-based items.
AT-205 contains no petroleum distillates and will not cause seals to become gummy and eventually break down. AT-205 RE-SEAL™ will replace over one dozen different single purpose leak products.

When I pickup my 72, it was sitting for over 8 years.
It was leaking oil from everywhere, the oil pan, front main seal, timing cover(2 piece), valve cover gaskets, oil pressure guage, and rear main seal.
The engine was a rebuilt 383 with less than a 1000 miles. So, long story short, drive and enjoy our corvette's...Don't let them sit!!

Thanks everyone.
I picked up a couple bottles of the AT-205 on lunch today. I was told they were changing the bottle to an aerosol can sometime in the near future instead of the pour in type.. Not sure why.
