I was racing my ls/vtec turbo hatch when the oil light came on. I am running 15 lbs. of boost. One cam jumped timing and I have no oil pressure now. I think the oil pump broke and caused it to jump timing. Does anybody have any other suggestions on what happen and what to do to prevent this the next time? What do drag racers do to prevent this?

 

oil pumps go out all the time, u just need a guage, did u take take pump off yet to look if u smoked the inside?

 

is there a oil pump you can get to stop this

 

The timing belt probably jumped due to a cam siezing in the head.

So do you run a VTEC oil pump and do you hav a stock crank pulley?

Are you running an N1/CTR crank pulley?

 

They go all the time? We dont drive DSMs...

 

I had problems last year, I broke 3 stock gears. I was going to do a prodrive, but then I witnessed one of them break too. My motor last year was just thrown together as far as I know (owner before me bought pistons/rods and stuck them in)... I finally switched from my unorthodox pulley back to stock and didn't break anymore. This year I'm running another stock pump, w/an ATI Super Dampner.... hoping I don't have any probs.. I think bad balancing/shitty aftermarket pulley's are to blame.

 

stock vtec oil pump, u.r. crank pulley

i think we all saw that coming...that sucks man. the unorthodox pulleys are not harmonic and it messes with the balance of the motor. unfortunately more than just your timing is off. your motor is probably done or at least needs a serious rebuild.

and like muckman said, its not the pumps fault, its the pulley. go with stock or the ati next time.

 

They reallly should be taken off the market. Even if I had a race car I wouldnt put that pos on it.

I agree, the gains are so marginal that I don't see why anyone would run them, especially knowing the affects it can have on an oil pump. The shitty harmonics probably causes a loss of as much power as the pulley is supposed to gain in the first place...

 

well do all engines use harmonic pulleys?? because i agree, they shouldnt be on the market knowing the ill effects on oil pumps. if its just a honda/acura thing then thats cool stop selling them more our applications.

hard to have hp gains if they motor isnt even running

Also check underneath the cams at the journals, I've ruined a head that way after it jumped timing. Sounds like the crank pulley AND the oil pump...

 

thank everyone for the info, so I should put stock crank pulley back on, should I buy a spoon oil pump, they say they are made better, should I pull the aftermarket pulley off the alternator too and what should I check for when I pull the engine apart?

Put a stock (new) VTEC pump on and an OEM Honda pulley (NOT THE CTR garbage). The alternator pulley is fine to leave on there. I don't even think Spoon sells an oil pump, and if they do, it is just OEM Honda. If you want, you can port the pump exit and radius/backfill the 90* bend just before the exit.

You will most likley need a complete rebuild, assuming the crank is not damaged. It most likley is scored along with the cam journals, no way to be sure until you get it apart.

 

well, after reading this im pritty much scared **** less... when i got my h22 in the mail the stock crank pulley was broken.. so i figured if i was gona have to replace it i might as get a light weight pulley.. and ive been driving it off and on now for a 2 summers and now im boosted running light boost at like 7psi.. will all these pullies cause engine failure? is it a certain thing?

 

Spoon sells one that is suppose to be made of better materials and toda also sells oil pump gears that are suppose to be better. Do you think is should use one of these?

Take it off. Yes it's certain.

And victoriasamantha. Get an OEM oil pump from Honda.

Yes. Get the OEM pump from Honda. The Toda Oil Pump gear is made of a different material than the oem one that is nice added insurance especially if road racing and having the car over 65% throttle most of the time. It doesn't change the AMOUNT of oil being pumped, simply a better material.

My failed pump cost me 2 cylinder heads and almost 2 seasons of HPDE events..

 

Spend the money you save from the aftermarket gear on a good balancer...

Honda cranks have a harmonic balancer in it, never use another unless it's balanced
