i got my motor running finally and runs besides a misfire on cylinder 2 it has fuel and spark but not igniting. im gonna do compression test tomm. but what could this be l heard maybe egr or a tooth off on timing.

 

compression on cylinder1,3,4 all were 210-240 but 2 motor didnt even turn over at all and had 0. now if 2 isnt turning over obviously not gonna get compression. could this be something else besides a blown ring or something else?

 

If your starter can crank the engine to measure compression on 1,3,4; how is it that it can't crank when you put the compression tester into #2?

 

This makes NO sense.. the cylinders do not have separate cranks, it sounds like your number 2 cylinder has no compression. If I had to guess, I'd say its a valve issue.

 

x2 on valve

 

all valves were fine when l installed. unless l bent one at startup or the 10 miles l put on it test driving.

 

before l replaced the head l spun motor over all pistons where moving fine. and now all pistons are still moving up and down. ive checked with a long thin screwdriver. wierd thing is l removed header and turned crank by hand. motor at tdc only #2 valves are open. and not 2,3 like it should and each full revolution valves are opening but only single cylinder at a time instead of 2

 

sounds like a bad valve or somthing. id do a leak down test on cylender 2... if the valves are filled up with carbon that could do it but it all depends... and its a zero clearence motor so u would definitly kno if the timing was off. but anyways try the leak down test before u tear the head off.
