Lack of Power possible valve problem?

[scubawrstlr]

I have been suspecting the valve on my accord have been going since I bought the thing. Anyhow its a 90 ex with 156,000 miles under its belt. So, when I first bought it there would be a little smoke around start up, and then it would burn off and run fine. well about a month ago I was driving and all of a sudden it started to lurch and jump, and it made a horrible knocking noise. Well I got out of the car, popped the hood, and the plug wire was sitting ontop of the vavle cover. Anyhow, the middle of the plug shot out, and compression was comming out the top. I drove the car down the road to my girls, and replaced the plug. Anyhow, now the car smokes extreamly bad untill it gets up to operating tempuature, and it still blows bad when I'm in stop and go traffic.

I think that it is the valves, vavle guides in particular, but I want some advice before I go ripping my head off. Thanks.

Oh, I forgot to mention that I have next to no acceleration unless I really smash the gas. And everynow and then it pops, but I figured if its the valve guides in that cylinder, then perhaps the oil and gas might accumualate causing the spark plug to foul up every now and then. I donno, just a guess.

I thought you were going to part this car out. If
the picture is reality, spending any money on it would be good money after bad.

Sounds like your cheapest and fastest bet for that motor would be to pull the head, visually check the cylinders and pistons for damage, (cracked piston, broken ring, cylinder wall scoring, out of round hole, etc.) and put a known good salvage head on it and hope for the best.

You need to run a compression check, if the pressures vary wildly from cylinder to cylinder, put a few cc's of oil in the low ones and crank the motor over a few times and retest. If the compression comes up, the problem is in the bottom end, repairing the head won't help.
