How can you tell if you have bent valves? NSFW
 

Well I’ve spent about two weeks cleaning up my engine I painted the bay and the motor and cleaned up all the grease and oil that’s built up on everything for the past 15+ years and then I swapped out a shot Trans then changed out my timing belts and water pump.

I had the entire wiring harness off the engine and out of the car I took off the fuse box pretty much anything I could take out without to much trouble I just removed and taped up the rest.

The problem is my car runs like ass and I hear valve chatter and noises that weren't there before. When I first cranked the motor I though I heard the valve hitting the pistons it was just a real nasty sounding noise but the car didn't die or anything it just wouldn't idle right and sounded like it was out of time.

Things I checked all of my grounds and plugs made sure everything was plugged in the right way and all the grounds were tight.

Then I took the timing belts off and put them back on and this time used a straight edge to make sure all the marks were perfect. It ran better when I started it. Almost normal but not quit. It doesn't go anywhere in boost but you can feel it come on and it gives it a little bit but nothing like before.

Now it idles a little higher then normal and it misses or backfires into the intake a little bit I can't really tell witch with the charge pipes on. I did a compression test and it reads 170 on all four but it used to be 190 still lower than normal but if I had never checked the car before I'd think it was fine for 8.8:1 compression??

I don’t know Maybe I have something plugged in wrong and I just not seeing it but it would have to be timing belt still a tooth off or I bent the valves the first time, but then compression isn't as bad as one would think for bent valves???

Anyone have an Idea of what I could have done?

what manifold is that?

^^^^ SSAutochrome's new....

"junkyard style". :P

On a b-series my buddys and I were working on the car didnt start after jumping a tooth. Ended up being bent valves. Wish I could give you more help but thats the only experience so far I have had with the question in reference.

Re: How can you tell if you have bent valves? NSFW
 

It's a stock manifold and turbo from an 04 evo. If you'll notice I had to move the alternator up to get it to work.
It's totally worth it though I only have it at 5psi right now and it made my accord as fast as my sisters gsr.

Re: How can you tell if you have bent valves? NSFW
 

I don't think it has bent valves becuase it idles and runs pretty decent. I had it out some last night and found a loose charge pipe. I fixed that and runs better but it still has problems. It could be just abunch of small things like that but it's still down in compresion acrossed all four cylinders. So somethings up.

Re: How can you tell if you have bent valves? NSFW
 

Could be cam or crank timing are still out a hair. That would account for a lower compression number.

Re: How can you tell if you have bent valves? NSFW
 

Thats all I can think of to. I checked everything with a straightedge though I guess third times the charm.
And I'd think if it had bent valves the compression reading would be way differant in each cylinder not the same?

Re: How can you tell if you have bent valves? NSFW
 

I don't know if the straight edge is the best thing to do, especially if when the cam's at tdc it has a slight angle to it. D-series single cams are like that, tdc is not flat across but rather a hair tilted towards the front of the motor. Check your manual...it should tell you which mark to line it up with.

What did you use to clean you're block/tranny/accesories with? you're engine bay looks real clean.

Re: How can you tell if you have bent valves? NSFW
 

In the manual it says to line the two marks on the came gear up with the top of the head. I sat the straight edge ontop the head with the valve cover off and lined up the cam. the crank is easier one mark on the crankgear and a mark on the block you couldn't get it wrong. Somethings wrong though I just have to find it. I'll take the timing cover back off and turn the motor and see If I can get it all to line up again.

I used brake cleaner and simplegreen to clean all the oil and grease off of everything then I just took everything off the firewall and innerfenders and painted the bay and the hood with white rustoleum. then engine an accesories I taped off anything that was black or a wire and painted it with ceramic engine paint. I made real sure no oil or dirt was on anything before I painted it. *L* I think I could paint a whole car with rustoleum and no one would know. It took me two weeks.

Here's my favorite part of the whole thing. This turbo is backwards from regular dsm turbos the intake side is flipfloped so I had to move the alternator up were the power steering used to be the the belt was right in the way on the intake side of the turbo. Fortunatly the guy I bought it from sent a bunch of extra parts he just gave me when I bought the turbo and manifold from him. The piece of charge pipe from I guess the evo works great for my intake it has the perfect bend to it and puts the filter right were the cruisecontrol used to be.
*L* it still has the BOV on it though I'm gonna take it off and plug the hole with something but I haven't got around to it yet.

remove cam



pour a ligquid into the cylinder head ports



liguid stays in port no bent valves


if its liguid tight its air tight



of course liquid starts pouring out at the seat bent valve



white trash troubleshooting

You’re a genius

Re: How can you tell if you have bent valves? NSFW
 

of course you would have to pull the head but ya that trick never fails learned it from the og honda builder. If you do have bent valves and the seats look staright just get some used valves clean them up lap those botches in and be done with it hmt way and well imo the right way has we all dont have fundage

Re: How can you tell if you have bent valves? NSFW
 

Well I have another complete head and a head gasket so it's not that big a deal. But hey thats a great way to junkyard test a head.

Re: How can you tell if you have bent valves? NSFW
 

use brake fluid.
and pressurized air from the top of the head (upside down)

Re: How can you tell if you have bent valves? NSFW
 

do a leak down test. pressurize your cylinders and if you hear air from the exhaust or intake manifold at TDC you have leakage from your valves or if you pull your radiator cap and hear it from there, its a head gasket.
