pulled the springs off and the valve stem seals are all smashed up, what could cause that?

 

I have a brute speed blower cam the specs on that are "dur @.050 232int/240exh lift .595int .608exh lsa 115"

comp 7955-16 pushrods 7.40"

comp 26926-16ts valve spring kit came with springs,retainers,valve locks,valve seals, and spring seals

stock rockers

comp 3153kt timing chain

heads and everything else stock as far as i know.

also im going to order the micrometer and start measuring everything asap

 

The micrometer will answer a lot of questions. Are all the seals smashed or only the one? Do you have the Comp trunnion kit? There are a couple of guys who had the trunnion kit bearings fail (one thread was very recent within the last week or so). You may want to examine that rocker more closely or possibly disassemble it if you have the trunnion kit to make sure all is OK. If the bearings start to wear abnormally it will change the rocker position relative to the valve stem.

 

The first two springs that I pulled the seals were smashed, ran out of time and stopped there. Yes I forgot to mention I do have the trunion kit as well. Ill disassemble the trunnion today and get a better look at it. and im also ordering the micrometer hopefully I'll have it by Tuesday at the latest

 

How's the fitment of the locks on the valve stems, and retainers..?

 

Hopefully some basic tear down and measurements will identify the issue.

 

They look fine they sit in there evenly, the micrometer should be here tomorrow from summit and ill be doing more teardown then

 

Can you post up more pictures of the retainer/locks. the fitment does look wrong. From what I can tell in your photos, the locks are too far in and there seems to be a gap all the way around the top of the lock. You may have super 7 retainers with the stock style 7 degree locks.

 

I was finally able to measure the first two install heights and they are right around what the install height is supposed to be



around 8.35



this one was closer to 8.36


and heres another pic of the retainers/locks.

does anything look not right from the pics?

 

You sure you have the correct retainers.
Look at the retainers that were posted earlier.
Totally different than yours.

 

See what I mean?

 

I would say they are suppose to be 1.800. That is enough off to cause issues. How many shims are under the seat.

they came with the valve springs in a kit http://shop.brutespeed.com/Comp-2692...6-16TI-KIT.htm
they do look a lot different then yours though.


I asked Bob at brute speed and he sent me a link from comp it says 1.835 install height is 1.8 a lot more common? I just have the seat and no spacers under it

 

IMO, it really looks like the retainers are sitting to high on the locks.

Your installed/seat height is correct, so that's good.

 

I wonder if the retainer was machined wrong?

The ones in the kit look to be different.

 

What is the diameter of the springs and retainers you have as this looks like a 1.400" Spring and that will not work in several ways

If you had this installed they could have shimmed them up to the right installed height for the springs as the retainers can have a +.100 installed height and that will cause clerance issues with the rockers

If you have a part number on the retainers only,that would help identify and eliminate some possibilitys

 

All of my valve springs set up under 1.800", typically around 1.765". The retainers are too high IMO.

 

The 1.835" is what Comp Cam recommends for the seat height with the 26926-16TI-KIT. So the seat height isn't the issue with those springs.
Yes the retainers are to high, but why...?

 

I talked to comp cams yesterday they said there shouldn't be any issues with the setup. Do the retainers look like the wrong ones? I bought everything brand new together maybe something was packaged wrong?

 

The valve locks look okay, but it looks like someone ground down the valve stem tips or somehow used a shorter valve. Look at this Mast head and pay close attention to the valve tips and their height.
