Jumped time, do I have bent valves? Runs good

[Clinical]

resolved, didnt jump time afterall! was just a loose water pump pulley !

If you heard the valves hitting the pistons, its pretty safe to assume you need new valves at the minimum. With slightly bent valves your engine will still run. You really need to do a compression check on the engine, and make sure everything is sealing tight to be sure. Even if it is sealing you may run into issues with "hot spots" on your pistons where the valves made contact (damaging the surface of the piston). These hot spots might show up as knock down the road. I know this is not what you want to hear but at the very minimum you would need to check the compression for me before I could give you my best advice.

Compression test or better yet do a leakdown test. Most likely you have bent valves regardless and will run like crap

Do a compression test and to help insure that nothings bent.

When I timed my friends 1g I forgot to count teeth and we ended up being 3 teeth off. Luckily we only did a compression test (which showed some F'ed up numbers), but after pulling the head the valves were all straight.

just a waterpump pully!

I skipped 2 teeth on mine and did zero dammage.

I retimed it, put on a new throttle body,sparkplugs&wires with a new front o2 sensor, Runs and idles like a brand new car.. Also has 170,000 miles on it.

So there is a chance it is totally fine.

Might be a pain in the butt, but best way to check valves is pull off the head. Better to be safe than sorry and mess it up worse down the road.

From what I heard, two teeth off and the valves will tap the pistons, three teeth of and your valves are being bent by the pistons, I would be careful running it too cause the pistons cause be salvageable even if the valves are bent.

I've seen more than one instance where a car will jump time, the owner assumes everything is OK, and a month or so down the road the valve guides will crack or break and you end up pulling the head off again because of lost compression in that cylinder.

I'm known for over-doing things, but then again I do not like to have comebacks on my work. I'd much rather pay a machine shop to replace the valves and guides in a situation where there has been known contact instead of putting me at risk of pulling the head again.

If you could hear valves tapping pistons you probably bent some valves or cracked some valve guides.
