Went to do a valve adjustment and discovered a cracked retainer.

Now I'm wondering whether I should replace my retainers with new OEMs or should I go with a set of Ti retainers?

Any experiences?

Thanks guys,

i recomend oem ap2 retainers.
i had to replace mine not too long ago.
i replaced them with oem.
TI retainers will need to be changed a lot more frequently then oem. about every 25k miles or so depending on the manufacturer.
it was a bitch when i did my retainers so i wouldnt want to replace them agian that often. not unless my car visits the track a lot.
as of today i am unaware of any cases of cracked/broken ap2 retainers on ap1 2.0 engines.
my pet turtle is bigger then my baby. hahaha

Ti retainers should be considered only if you need/want a higher RPM limit. They are less durable at normal RPMs.

What is the cost of new AP2 retainers, and how high of a safe RPM can be had with them?
Thanks :LOL:

:LOL: Another recommendation for ap2 retainers. I don't think we have heard a report of anyone cracking them yet, at least not with valve to piston contact, at which point no RPM will save you. Billman has stated this opinion and we all know how well he knows s2000's.

Has anyone has ap2 retainers crack on them yet, regardless of what motor they are on?

Aaron, do a search for "cracked retainers" and "Billman." AP2 retainers are the way to go, but I believe they have to be modified to work in the F20C. Billman can clearify. ;)

I thought the AP2 retainers into an AP1 head were pretty much install and go, what modifications are you thinking of?

No mods. Just use AP2 keepers with them.

Do the AP2 keepers come with the AP2 retainers, or do they need to be ordered separately? Sorry if this is a dumb question, I'm slowly compiling info and I might just do the swap on my AP1 for peace of mind.

retainers should be $2-$2.50 each depending where you purchase them. keepers should be $3 for each pair. they are separate parts and do not come together.. so $85-90 total

is the "keeper" the same as what Honda calls a "cotter"?
and am I correct in assuming that we need 32 pcs (halves)?

Wouldn't the F20C2 retainers do the trick?

Keepers/cotters are the same. You'll need two for each retainer, so 32.

Personally, I'll do AP2 retainers on the intake side only if I find them broken.

:LOL: My mistake. I thought the AP2 retainers needed a little grinding to work on the AP1.

Question for you and maybe also Billman.

Why do you think your retainers cracked?

Would retainers crack for no reason (no reason being never over-revving)?

i had my retainers replaced...but i don't remember if i got ap1 or ap2...i ordered from hardtopguy...should have made sure to get ap2's...oh well.

do you think hardtopguy would be able to pull up an invoice from 2004, assuming its all computerized and check for me? hehe, i guess i'll call him and ask...

I'm sure he will. Hardtopguy is awesome, I spent a long time on the phone with him today and we got on the subject of retainers.

Just to throw some fuel on the fire, he says he thinks the AP2 retainers will crack just like the AP1's do, and that he had a metal expert inspect AP1 and AP2 retainers to see if he should start recommending the AP2 as better and they found they were both pretty wimpy retainers.
