But whos to say the previous owner didn't? I'd at least check them out to be safe. FYI: sometimes the cracks can be hidden and only visible if you take them out.

It has 150,000 mi and have a cell, previous owner said it was misfiring, 3out of 4 coils/plugs were changed by him and a valve adjustment, so ill do the fouth if that aint the problem then ill probably do the springs and retainers...?

replace ap1 intake valves with ap2 retainers and ap2 keepers
replace ap1 exhaust valves with ap1 retainers and ap1 keepers

the ap2 retainers are not good for ap1 exhaust valves due to them being heavier and increasing the chance you'll have valve-piston contact.

not sure about the springs, i reused my stock ones.

Wouldn't it be make more sense to replace both intake and exhaust retainers with titanium after market retainers since labor is probably the biggest part of the cost in that job?

titanium retainers are not as strong over time than OEM. you will need to change them more often, not really desirable on a street car.


i changed my ap1 intake retainers at ~60k miles and they looked fine. with that said, i'm definitely going to pull the cams and do the exhaust retainers since i'm at 100k miles now.

cheap insurance, just got on majestic to check prices,

$69.17 after S&H.

your springs are fine. do not waste money on springs..

the parts you need are:

intake side:
8 ap2 retainers
16 ap2 keepers (cotters, what keep the retainer on the valve stem)

exhaust:
8 ap1 retainers
0 ap1 keepers (re use your old ones)

I've never heard of this being necessary on an AP2 other than normal valve maintenance (at probably around 100,000 miles). Any thoughts??

I don't think so either Jim. The AP2 retainers are stronger than the AP1's.

unless your valves are already bent and you're having problems (like misfire CEL codes, car runs bad, etc) then no. to do valves you need to pull the whole head and it's a lot more involved vs. just pulling the valvecover and doing the retainers. retainers can be done in a couple hours, valves are going to take much longer.

err, it doesn't really work that way.

valves changed? if they have made contact with the pistons they're going to be bent, being bent means they're not going to seal 100% and your car is going to run badly and most likely throw a check engine light.

valves adjusted? if you do retainers, the valve lash will need to be adjusted.

if you're not doing retainers? it's really just up to you.. the service manual says every 105,000mi the clearance needs to be checked.
