Ok was driving back on i-5 from la to sac, and i started to loose power, was goin about 80mph at the time driving normal, and suddenly hear some wierd noises, pushed in the clutch turned off the car, but too late What happend is my titanium retainer some how broke as you can see in the pictures, They are portflow retainers!!!! Not sure if they will do anything to back up their product about this, but im pretty upset. Anything i can do? ive had these retainers in my car for over a year now. The skunk2 valves seemed to hold up pretty well, they sure beat the piston and head to death

well for the sad pics
anyone else ever seen a retainer do this?

Not sure what im going to be doing now, i know i need a head for sure, and pistons, the cylinder walls dont looks that bad. Setup was jun3 cams, jun springs, portflow retainers, and skunk2 valves.

 

ouch, sorry bout that

 

eeeee....that looks bad amigo...sorry about your motor

 

!

 

not a pretty site to look at

Be sure and let us know what portflow has to say.

 

Chad had some Ti retainer problems too I think.

*goes to get Chad*

 

WOW! Did you clay it when putting it together? Those pistons look beat.

 

yea there was no clearance problems at all, how can you see the pistons when they are covered with oil. Also i just checked the retainers, like 3k before this no sign of any wear.

 

sorry to see that man

but new motor for new year

 

Man, that looks bad... I hope Portflow can help you out.

 

Damn man...

 

Titanium is reactive with a few metals and actually starts to begin to loose its strength when it comes into contact with Chrome Vanadium (metal used in a tools like wrenches, ratchets and such.) and many other well known metals and alloys. Titanium retainers are generally for race only since after arace the engine gets rebuilt anyway, for street driving this is totally expected. Im actually surprised that more of this doesnt happen. Anyway sorry to hear of your loss. Good luck with portflow

Edit - Grammer and such.
Edit - Added the tools thing.

did pieces of the retainer and valves get sucked through the intake manifold into other cylinders?

This is what someone i trust tells me. He works with materials in the medical industry and thus they dont use titanium as much as they used to anymore. Anyway stock retainers hold upto the high rpm just fine from what i hear, you really are changing out retainers for weight savings and I wouldnt risk it

 

I remember someone else who has portflow Ti retainers had a problem with them too...After a short amount of time, they thinned really bad. HTH

 

That was chad (TodaSi) who had a similar problem, but I don't think his were portflow. They were nearly paper-thin.

How many miles on your retainers? Here are some pics of my portflows. I had Toda B cams in there for a little over 20K miles (I am now back to stock cams for unrelated reasons). You can see there is still plenty of thickness left. This is imagestation so you will need an account to see (free). Someone can host it for me?
