Titanium retainers
Hello Guys
I tried serching but it's not working. My question is, How long to titanium retainers last. What I mean by this is, do they wear out over time and may drop a valve. I am running toda spec c cams, vavle springs, and titanium retainers. The motor has about 10k on it already. What do you guys think.....thank you kosta

Re: (atg1290)
I am also curious a bit about this. I am using portflow Ti retainers in my motor and I have recently heard some horror stories about dropped valves.

Re: (LSvtecMike)
generally you would want to check them as often as you want to take off the valve cover........ maybe every 5k or so...... on a daily driven car they start to have troubles around 20k........ but some people arent even that lucky and dont make it that far
i would just check them over real good every oil change......... it only takes like 10mins to pull off the cover check them all over and put it back on...... so why not

thickness of the spring seat on the retainer........... i know YOU know this....... maybe you just wanted me to explain it to someone that may not know?

Re: (JDMlyfestyle)
Aren't the stock ones be sufficient for most applications anyway? I mean are the titanium ones really that necessary? From the reading I've done on HT though it seems like the wear thing is exaggerated and most people don't have any problems.

well i wasnt gonna badmouth anyone else. cause ive seen SEVERAL post on here over there years with people complaining about **** 2 springs and retainers. they supposively fixed that.
But go ahead and post up the companies as long as you got the proof on it. cause there has been some extreme amount of bashing companies here lately

Ill say this.
If there is valvetrain failure, usually the end result is catastrophic and its a big mess. You can sometimes trace it back to a bad retainer, maybe excessive guide wear causing a little too much wobble, maybe a spring was weak from just being old or even over revved a few thousand miles before. Sometimes guys bounce retainers off seals and then blame the retainer. Did the retainer fail? Yes. Whose fault was it? Whoever put it together.
I dont have documented proof, per say. Just my word, what i have seen with my own 2 eyes, not just read on internet forums.

Re: (cjames235)
I have personally seen multiple ti retainers groove up and wear thin. Multiple company's (crower, skunk2, supertech) but most are made in the same factory. I have been using the crower cro-moly ones. They are an exact replica of the ti but made in cro-moly. I think they cost around 70 bucks, but in my drag motor i used stock retainers and surface ground them thinner so they didn't bottom out on the valve seals. The only way you can tell if they are wearing out is to remove the retainer and look at them, you can't tell just by pulling off the valve cover. Sometimes it is the inside seat that wears also.

Re: Titanium retainers (costar)
Thanks for the info guys. What type of vavle spring compressor are you guys using to be able to remove the retainers without dropping the valve. I heard of pressuring the combustion chamber, but I'm looking for a clean and easy tool.
Another word, from what I am hearing, oem retainers will do just fine, and last longer on a motor that will be revving to 9300rpm. In that case I'll be changing over to oem, so I don't have to worry everytime I drive my vehicle.

Very good info, I will have to take a look into the crower cro-moly retainers some time this week. Would these last longer than titanium in my daily driven engine with Blox B cams? If not what would be some better options for use with high lift cams.

Re: (Combustion Contraption)
I just took a quick look on crowers website for the cro-moly retainers. They don't seem to be listed there. Where can I buy them from?

Re: (LSvtecMike)
how much more reliable are the cromoly ones? is there any worry of wearing thin like with Ti? basically can they handle the abuse of high RPM's any better then Ti?
