Installing ZZP ER Rocker Arms??

**Kerker48** · 10-14-2009

My job this weekend will be installing a set of ZZP ER Rockers (1.85 to 1 for the intake valve and 1.80 to 1 for the exhaust valve) on my L36 engine.
I have two new coolant elbows,new rocker bolts,and gaskets coming with the
rockers also have all the torque specs.(thanks to VinnieGTP for posting and Andrew 99 GTP for asking).I just have one question would it be less messy if I
drain like a quart of antifreeze from the radiator so the fluid is lower in the block when I remove the coolant elbows? Any other helpful input on this job would be great.

If your going to drain a quart...might as well just drain it all out and flush it...probably wouldn't hurt either. Especially if you have Dexcool in it...if not...just drain it out until it stops...just makes life easier and LESS messy trying to plug it back up while it is draining. You are still gonna lose some coolant that is sitting up top though...just a FYI.

Dab a little rtv on the valve cover gaskets to help hold them in when you put the cover back on.

Success!! Not to bad of a job glad i got the coolant elbows top one broke
when I was taking the Alt. bracket off had to dig it out of the intake.Also flushed the coolant system took about 6 hours to do everything.Didn't take for ride yet it is pouring rain here hope it's sunny tomorrow.TY for
your input.
