the cam is probobly bent. that or there are obstructions on the lobes making it harder to turn.

 

bent valves.. shot head... broken piston... bent cams... looks like time for a complete overhaul.

 

pics?

 

i have the distributor off of the head and im just turning it with my hand and its pretty stiff so i dont think its my cam. i havent had a chance to get pics up my friend hasnt come over with the camera yet.

 

Check out the latest issue of honda tuning. THe guy lost a timing belt and demolished his engine. But they show the rebuild, including cleaning and welding the cylinder head, it actually didnt cost a much as i thought.

Looks ok to me, slap it back together

Ouch

 

A moment of silence please.......

 

*stands back in shock*

 

damn

that's not good... sorry about that

 

Damn.... aren't Toda A's compatible with stock Valvetrain like the Skunk2 Stage 1 cams?

I've been running Skunk2 Stage 1 cams in my GS-R with stock Valvetrain for about a year now. I redline my car all the time and push my car alot, yet the car sounds and feels perfectly fine.

But reading this story got me scared. I won't push my car that much until I get a Valvetrain upgrade.

 

From Toda's website:
"*TECHNICAL NOTE
All TODA Racing camshafts must be tuned using TODA adjustable campulleys to attain maximum performance. Valve lash for all cams is 0.2mm cold. Spec B & C camshafts require TODA valve springs. For Spec A camshafts, the following Honda/Acura valvetrain components maybe used up to 8400rpm on both the intake and exhaust side.

VALVE SPRINGS-Inner :14751-P73-J01 x 16
ALVE SPRINGS-Outer: 14761-P73-J01 x 16
RETAINER: 14765-P30-000 x 16

With Spec A camshafts if engine will be operating beyond 8400rpm, TODA valve spring kit must be used. Using Spec C camshafts on engines with milled cylinder heads, thin head gaskets, or non TODA Racing high compression pistons may cause valve-to-piston clearance issues. For maximum performance, Spec C camshafts must be used with TODA high compression pistons and upgraded fuel injection system. Some aftermarket campulleys use connecting bolts that are not compatible with TODA camshafts. The use of these bolts could damage the TODA camshafts. If you plan to use TODA camshafts, we only recommend using TODA campulleys to prevent damage to the camshafts.

The TODA High Power Timing Belt is highly recommended when using Spec B and C camshafts."


Toda "A"s are o.k. with an almost stock valvetrain.

 

Toda clearly says that the spec A's need to be ran with type r vavle springs, they tell you that for a reason. Gsr vavle springs are not strong enough to handle the spec a's.

 

you say youve had your cams in for about a year?....i had mine in for 2 days. but thats my fault. the guy i bought them off of said he was running a stock b16 valvetrain for a while now and i trust this guy so we just went ahead and put them in. it sucks...but ya live and ya learn.

 

looking at that damage seems far from simply mechanical failure under normal conditions... I smell No2

I know, story scares me too. I have CTR's on my stock B16 valvetrain with a Kenji P28... i've seen 8800 rpm's quite a few times already, only had the ECU for a few weeks.

Jake, who's next mod is an upgraded valvetrain.

 

you smell no2?...im not spraying pal

If I blew my ****, I would admit it was my fault. In fact, let me get it out of the way now. on me for having stock valvetrain with upgraded cams and 9200 rpm redline. me, me... me.

 

sleeperciv: did you read through the whole post?...because im pretty sure i already explained to someone else what happened with that

im not afraid to admit i screwed up...but in this case the only thing that i really messed up in is the valvetrain...i didnt over rev i didnt mis shift and im definitely not spraying
