I think it is worth mentioning that you should check/replace the fuel filter/ water separator filter, you could be getting bad gasoline (water in the fuel)

well, i ordered a new pushrod today and the msd blaster 2, so i will have them in a few days i don't know how to upload pictures, don't have a pic site.....
when i took out the pushrod today i noticed the rockers were extremely loose, are they supposed to be that when the engine is not running?
and the fuelfilter is new

the procedure for adjusting them is on the internet, google it. its very easy to do. there should be zero clatter once they are adjusted properly. you can loosen them on at a time with the engine running, then adjust them til they stop clattering. rm

Toylux,

Setting valve lash/preload accurately requires that each lifter be on the base circle of the camshaft to ensure the valve is fully closed when you adjust the lash/preload. The foolproof method is to remember "EO/IC", which stands for Exhaust Opening/Intake Closing. Run one cylinder at a time. First rotate the engine observing the exhaust valve. When the exhaust valve just begins to open, stop cranking and adjust the lash/preload on that cylinder's intake valve. Then, rotate the engine again, observing the intake valve of the same cylinder. As the intake valve moves past peak lift and begins closing, stop and adjust the exhaust valve on that cylinder. Repeat on each of the remaining cylinders.

If you are lashing a solid lifter cam use a go/no-go on your desired lash setting. Setting the preload on a hydraulic camshaft requires tightening the rocker adjustment slowly while rotating the pushrod between your thumb and forefinger. When you begin to feel the pushrod tighten, add the required preload to the plunger. Be cautious to not preset any rockers prior to adjustment. As you rotate the engine to adjust the current cylinder, it may compress the adjacent (yet to be adjusted cylinders) plungers, purging the checking fluid /oil in that lifter making it difficult to determine when the pushrod and cup are at zero preload.

^^^^^^This is the gentleman you need to talk to about a new roller cam and ALL related valve train components . Great prices and a wealth of knowledge . He is by far the very very best .

hi' thanks for your post rmbuilder i have adjusted when running as mentioned, but i know that is not very accurate but it can't be that far off? it seems like my lifters bleed dry over night because there were much slack when i took the cover of again, but when i started up again they looked fine.. but i don't really know what's normal :P i'm a scania mechanic so i only wrench on v8 diesels :P
i'm still waiting for the pushrod so i don't know if it will solve the problem, but can you recomend a complete cam,lifter,rocker and spring set rmbuilder?
and to all, i really appreciate all the help i get

thanks again.

You set the lifters when the engine is not running for best results now days.

Been a long time now. The engine is teared down and many problems are found
does anyone know of shops in texas that sells mercruiser, comp cams and msd parts?
my cousin stays there some days too and from his work in the gulf.
thanks again

Get with rmbuilder. He will get you the right stuff. Have it shipped to your cousins office with his name on it.

He just stays in a hotell, his office is on the ship
