woot thanks soo much 91siz6

 

it sounds like you may need a rebuild. is it getting worse?

 

Also i would check the timing to make sure that the crank is in time with the cam. That was my problem. fixed it and all was better. Did a compresion test everything was ok.

 

update i just got done lashing the valves and i decided to move the timing a bit with the dustrib it sounds alot better at idle and mid but at higher rev it sounds like a rod in the head it used to sound like a bunch of monkeys hiting cymbls now it just sounds like one big monkey..im thinking mabye timing jumped a tooth tell me what you think plz

"It sounds like a bunch of garbage men playing cards"

what in the hell kind of sound is that? you're gonna need to describe your sounds better, man. relate the sound to something i've actually heard before. i've heard a lot of things, but numerous monkeys playing cymbols isn't one of them.

*chuckle*

OP: You check the LMA's too?

 

well if i was trying to trouble shoot...i would make sure the timing is set to spec first and go from there. any loss of power?

"i've heard a lot of things, but numerous monkeys playing cymbols isn't one of them. "

oh man are you missing out! haha thats funny stuff.

 

Cymbal. With an "a". Sorry, been playing drums for almost 20 years and it's a pet peave.

Set your crank pulley to TDC on the #1 cylinder (use the like I gave you) and make sure that the cam gear is lined up at TDC too.

edit:
Forgot the engine was a D15.

What? Dude, a "vtech" is not going to help you fix a spun rod bearing. I'm confused.
