Maybe start with regular maintanence before you start diving into serious engine repair get a service manual and someone who knows about cars to help you, your never going to learn anything from taking it to a shop, but this project is pretty involved so it might jus be better to pay someone for the rest of your engines sake. It's a toss up really if you think you can do it with someones help go for it. use the dipstick it is there for a reason!

i could here my valves before i did the isr mod. are you sure the "really fast clock" sound isn't the normal engine sound? it could be possible that you are just more concious of the engines sound now.

wait did you drain the excess oil out?

I'm not sure why a previous poster recommended not doing a compression test but I sure would if I were in your shoes. Tells you a lot about engine condition. For example are all valves seating correctly? Are all rings sealing. Like others said, get yourself a maint. manual and read up.

awesome. keep talking this is very helpful. I've been doing tons of research. It's not text I need, it's experience. At idle, occasionally the engine will shudder and in gear it will sometimes clunk at low speeds. The smoke is all gone at idle, untill I lay on the throttle

I cleared all the smoke out, and when I start to work the engine it hiccups and soon more smoke starts to burn. I'm thinking I have a valve that is partial and needs to be replaced. But why is there excess oil in my dipstick tube?

PS, the new burning smoke burns off shortly at idle

I said I wouldn't rely on a compression test to determine the state of the rings because: if the oil control rings were shot or otherwise compromised they would allow oil to bypass themselves and would cause false test results (a.k.a. "dry" test) without having to add oil through the spark plug hole because the rings would be adding oil themselves.

The compression tests could come out perfectly fine, since you're testing the compression rings and not the oil scraping rings... and if the oil scraping rings aren't 'scraping oil' from the cylinder walls... compression tests will probably be better than what you'd expect doing a 'normal' compression test.

Low compression does not always mean burning oil and burning oil does not always mean low compression.

Hmm. Makes sense, thanks for the explanation.
