i have a 94 camaro stick shift trani, when the car is cold and i turn it on the engine sounds good but when i drive it for a while and the engine starts to heat up it makes a ticking sound pretty loud , is it my oil?
could very well be an oil breakdown issue, especially if you haven't changed it in awhile. Change it. Worst case is that it doesn't fix the problem.
edit: it could be a leaking exhaust as well. Sometimes exhaust gaskets start to leak after they get hot. Depends on the where the tick is coming from.
Its definitly a thin oil problem. Also a weak lifter as mentioned. If you want to keep the car I would buy a cam kit with lifters and replace it and then get the high volume oil pump and you should be good to go. since your pulling the heads to do all this you might as well get the valves done and new rings put in. all can be done with out pulling the motor.
