Ok, i don't know if it was the heat or my A/C or whatever but this is my episode.

The past couple days I've notice everytime i started my car, the oil light would stay on for like 4-5 seconds.. this kinda scared me because that's about 5psi oil.. very low.. but the car didn't sound any different.. still ran hard.

Today, i was on the highway going 80-90km/hr (55mph) and was in 3rd flooring it.. then shifted to 4th like usual.. then a pop sound and felt like clutch slipping or i wasn't into 4th properly.. then the engine died... i coasted to the side and waited for tow truck....

I tried to start it despite what i heard about not starting in case it was the timing belt that went... the starter just "spun" no cranking, just "wheeeeeeeeeeeeeee" so i said **** it..

when i got my car home.. i found one intake valve broken... hell's know if anything else is wrong but probably is.. this should be covered under warranty but i just want to see what would cause this?

observations:

timing belt OK, not snapped
Cam gear is OK, not slipped
Cam is ok, nothing wrong.

I also noticed everytime i'm near redline, the car sounded more louder and more vibrating than before the past couple of months....

what could cause a broken valve?

1. Valve float (at only 6700 rpm?)
2. Valve lash adjustment too tight or loose???
3. The cam's vtec profile too strong??
4. Cam retarded 2 degrees too much?

That's the only things i can think off.. but i ran it like this so long... i think it has something to do with my oil pressure.. maybe my car had problems from beginning with oil and starved my engine or something..

I also always since the beginning.. got like "hard" starts.. like cranking the engine was very "sluggish and slow" cranks... and when it turned out, sounded like not enough fuel and was gonna stall.. and also the oil light was on again for 2-4 seconds...

what you guys think???

the valve just broke off! it seems like it's still holding and not dropped into the cylinder.. i have no idea how it stays.... retarded...

 

What motor do you have?
