timing cover
 

do any of you know of any 2 or 3 pcs cover other than comp cam that would fit a gen vi at a reasonable price?
been looking on the internet without luck.
and what would be a good adjustable single roller chain set for a gen vi ?

someone must use 2 or 3 pcs timing set cover(gen vi) other than the one made by comp cam?

I had the same problem trying to find covers for a Gen 5. Nobody makes them. As far as I know, Comp is the only one making multi piece covers for Gen 6.

did you consider the Milodon gear drive, it has a 2 pc cover.

Re: timing cover
 

no i haven't.
is there advantage to go gear drive?
someome told me they were very noise,true?

Re: timing cover
 

I've run them on mark 4 and gen 5 motors, they are very accurate as far as the timing, they don't jump around like a chain, and they last forever. The Milodon has one gear on a shaft, mounted to the housing,that fits between the cam gear and the crank gear. I doubt you would ever hear it in a boat.

If you going this route you would be better off just to go with the Jesel belt drive.

how long does the belt last in a marine application ?

Re: timing cover
 

Gear drives rob HP and cause unwanted valvetrain harmonics. Timing chain or belt drive.

Re: timing cover
 

thank's for the inputs guys.
i noticed would need a three pcs cover because can't pull the balancer in place and budjet does not permit gears or belt system at this point,so will stick with stock cover for now.
appreciate all your inputs.JP.

Re: timing cover
 

I don't know, I wanted to run the belt drive, when I called Jesel they told me to change the belt every 60 hrs just to be safe. There's a lot of valve spring load with a solid roller. I can only imagine what will happen when the cam stops turning and the crank doesn't. It is all in what you are looking for, $800 for the belt drive, never know when it's going to break, $500 for a gear drive run it forever. To each his own.

thickness is the issue.
A 3 pc cover has to have a ledge between the upper and lower cover to bolt to. chain runs too far out front to allow a ledge. if you run a crossover or space out your circ pump I can make you a 3 pc cover. (you'll also have to run a custom circ pump pulley...)

I don't advise to use gears. Harmonics are hard on steel cams.
