I split your post asking where to buy engines, it's in Coffee Shop. Unless we're gonna continue to troubleshoot your car, we should probably CLOSE this thread.

I need to start this post up again. I replaced my timing belt and water pump and put everything back together. The engine is cranking well but no start. I'm assuming that I have fuel and spark since I sent a fireball out of cylinder one when I pulled a plug to test. My fuel pump is priming and seems to be working.

I'm thinking that I flooded it out when I tried to start it without many of my vacuum lines hooked up. My spark plugs smelled like raw fuel so I pulled all my exaust plugs to let it air out. I'll clean a replace my plugs and try again tomorrow.

Any ideas?

Have you done a compression check yet? Spark, fuel, etc will still be present, assuming that wasn't the problem- your car was running fine before- but if the valves bent, you'll have little to no compression.

I haven't done a compression check, I know its important but don't have the tools. I took a break from working on the car. I'll spend some time on it tonight, I sure I can get a compression tester if the engine still won't start.

you should be able to borrow one from autozone/parts store. It will tell you all...

I just bought a compression tester and am going to go test everything now. If I do have bent valves is there any reason I can't pull a head off another ca20 and bolt it on?

Yeah that should be fine. Might be easier and cheaper than rebuilding your head.

Well after a compression check I know I have bent valves. I need the car to run to I towed it to the shop tonight. I know it won't be cheap..... shit.

Anyone know a fair price for this kind of repair?

if i had read this i could have told you that when you break the timing belt the head is done.

when i broke my T-Belt indicated by whooring buzz noise and the rapid engine start rate(more then normal) also it was allot quiter indication of low or no compression.

i had split 2 valve guides and bent every exhuast vavle.
and this was a CA18ET motor. as i look at this it was good thing, later upon disassembly of the motor i had so much clearnace in my con rods that it shocking that motor could run with so much slop. litteraly more the 1/8th" of clearance in some places.

these are my thoughts

Turns out all eight of my valves are bent. The shop said it will be $700-$800 to fix.

If you aren't ready for a swap just install a used head from a pick and pull. But what was stated earlier by others users is direly important. There were differences in the MKI and MKII heads trust me I know I dropped a 88 MkII in my 84MKI and bolted the intake manifold along with the tranny then found out that yuo have to swap over quite a few parts and what nots to get it work right. From what I remember is that MKI CA20's are black top while the MKII have a silver top dunno how much it'll help but unless you got a CA20 that was babied into it's old age you are about to start on a long journey of maintenance and hardships, trust me I love my CA20 in this car in my other one it was a pain. You learn from your mistakes.

i recently got a ca20e head for about 100$ from the salvage yard, a pull-a-part will be even cheaper. i would recommend replacing the valve seals and maybe even a valve grind before installing an unknown head. you could get the head and have it reworked for around 200$, much cheaper and easier then a swap. good luck!

I dropped the cash and had it repaired. My gf drives my s12 and I needed it working asap. I still have two years of emissions testing left so I'm going to save money untill then. I have plans to do paint and suspension untill I don't have to pass a sniffer test.

The good news is my engine is running like new and it feels great to drive it around again.
