CTR vs BuddyClub III cams

[Vteckidd]

I adjusted the clearance between the cams and valves myself: setting Intake at .007 and Exhaust at .008. with an oem head gasket.

You did a valve adjustment, thats not setting clearances. Not ones that matter.

Degreeing a cam in is not the same as doing a valve adjustment. at those numbers there is no way you had contact. THere is no way BC3s hit CTR pistons with an OEM spec valve adjustment.

WHat were your cam gear settings? you could go +/-3 an have no contact on that setup

My car was un-tuned and ran fine for days with minor issues dealing with the ecu, but was driving it hard one day and 2 of my intake valves had dropped and shattered 1 of my CTR pistons

Sure it didnt detonate and torch a valve? sounds like it to me. ECU issues, 11.5:1 compression, untuned, revving it out

Sure your timing belt didnt jump? who set the tension?

You sure you didnt pull a guide through? have you looked at the guides in the head?

break a keeper? break a retainer?

From my personal experience BC3+s are not that aggressive, you should have had contact unless the head was milled way out of spec

Excuse my previous statement. With a filler gauge I was able to measure how much space there was between my cam and the rocker arm (once again excuse what I stated before) and then adjusted with the stated numbers. The head was taken completely apart when I had got it back from someone on IA and know that those are not stock cams some adjustments where needed, just like it says on the BC website of what the desired clearance between the rocker and the cam, but always take it down 1 so originally Ex was .009 but since everything was new and everyone knows that when metal heats up it what....... expands until it reached its limit (or something like that ) so if it to far and at one time it was you'll hear a lil knocking noise from the head and of course you'll already be able to diagnose the problem just by the way it sounds.

Didn't recall me stating that I changed the degree in the cam because I couldn't it was stock SI cam gears, I had adjustable cams on before that, but then took it off, but that was months ahead of that.

Nothing, Stock Cam gears

I believe that my compression was a bit higher than that like at a mid or high 12's and revvs where meaning I took it to 8.5 if not 9 rpms.

Sure your timing belt didnt jump? who set the tension?

yea it didn't jump after I had put the belt on to make sure that it had not to much slack between the intake cam gear and the water pump, I have and neighbor who's a honda-tech and asked if he could check behind me for reassurance.

You sure you didnt pull a guide through? have you looked at the guides in the head?

Yep when I pulled the head out to see if it was able to be machined (I'll post pics) it did not pull a guide through it only cracked one of the guides, but they are still in place

break a keeper? break a retainer?

nope and nope all of that was still somewhat intact. When my car turned off as I was driving besides the noise I heard, I knew that it wasn't good. So on site of the accident one of my squad friends had a tool box in the back of his car which came in handy. I imediately pulled off my vavle cover to feel the rockers checking to see if I bent or dropped a valve and of course you know that you can check like that because there will be soo much play between the rocker and the cam that it wouldn't make sense and I was sad to figure out that when I came around and felt #2 I was able to move the rockers freely up and down

From my personal experience BC3+s are not that aggressive, you should have had contact unless the head was milled way out of spec

ok pics are below






I thought it was 2 intakes but now as you can see it's 1 intake and after I kept moving my head around the piece of valve on the exhaust broke off lol, but there it is. I'm pretty sure it did more damage before I came to the conclusion that my compression was lost due to the valves and tired to crank it back up 2 more times just to make sure it wasn't anything else adding to the situation.
