Hey all,
Fitting roller rockers and a new head to my 202 with hardened 186 pushrods...just a throught, i have hydraulic lifters for 202 in the 202 at the moment, am i able to use them with my new 186 pushrods and roller rockers or do i have to get 186 lifters? Are they the same and if not how do they differ?
Another thing is that if i need new lifters...will i need to 'prime' them in any way 'ie fill them with oil' before i plonk them into the slots?
Cheers,
Brad

to prime them...do you have access to a pedestal drill?
Get a steel can and fill it to a bit above the height of a lifter with oil, put an old push rod in the chuck of the drill and then wind the chuck up and down pushing on the lifter plunger to get the air out.
If you dont have a pedestal drill just leave them sit covered in oil over night and hope for the best.

Yep just use the same ones.
To answer your other question just for the hell of it, no you dont have to prime new lifters, but it is better to. All you do is fill a small container up with enough engine oil to cover the top of the lifter, stick one in, get a screw driver and push down on the little dimple where the pushrod sits in. Just keep pumping till no more air bubbles come out, usually around 30 seconds. If you dont do this then they will just be a bit noisy for the first minute or so running, plus your rocker gear wont be getting any lube.
Cheers.

While the lifters are out you may as well put in a bigger cam

Now that I have read and understand your original post...you don't have to do anything..just drop your new pushrods in and set the lash.
Interesting article up the back of last months? street machine...it suggests seting hydraulics to zero lash and not preloading them.

As to pre loading them, IMO i would follow manufactures recommendations as this can vary from product to product.
There has been some changes in product design over the years.

I never preload - just adjust to take up clearance.
