thanks

thanks guys

Remember if you ever lose oil pressure the chain is going to jump time. Don't skip those oil changes!

Why on earth would you think that a CHAIN would jump teeth from lack of oil pressure.

Because the tensioner uses oil pressure.
The fits are too new still but we have done many Accord engine repairs/ replacement because the oil level got low, lost pressure, and the chain skipped a few teeth due to the lack of oil pressure.

i dunno. every time i start my fit for a second or two it has no oil pressure, so if what you're saying is true, wouldn't it jump time every time? considering things are cold and it's harder to get them spinning? i dunno. just a thought.

It takes very little oil pressure to keep the tensioner working. It has oil pressure as soon as the engine is turning so no it will have pressure as the engine is starting and cold.
But it is 100% true that low oil/ pressure can make the chain skip.

Ross 2.0 better Check your repair manual for a Honda Fit/Jazz L-15-a engine or try taking one apart. They all use a MECHANICALLY tensioned rubbing block type cam chain tensioner. NO oil pressure involvement in tensioning the chain what so ever. It's tightened to a mechanical torque spec and locked down with bolts.

No oil pressure is directed to the chain tensioner. There could be NO oil or oil pressure and the chain would still have the same tension ALWAYS except for normal wear and stretch but that is taken up by spring tension in the rubbing blocks.

Sorry you need to check your information. I even went back and checked. It uses oil pressure.

I'll second Ross opinion.

Confirming or denying?
We have an accord in the shop right now where the insurance company is fighting us. Of course it's a K20 engine. But when the motor comes out of the car I'll make sure to take pictures of the tensioner and the oil line that feeds it.
Want proof? Here ya go.

found one.. i believe you now ross. i didn't before. but i finally found a pic of one..

spoonfedcrx

I was confirming. I've done my fair share of engines in late model accords that all have had timing chains jump and smash valves. All seemed to had one thing in common. Slightly high mileage 90,000-120,000.

Another guy at my work has a fit that is in the same boat. Only has 11,000 miles on it but the thing is beat to hell. Looks more like 150,000 on it/

Good to know information, that one looks like the one in the Fit manual.

Claymore is correct.

First, the iN Online University screen snapshot you posted is of a "1.7L 4-cylinder" engine.

The Fit uses the L15A1 1.5L I4 VTEC in 2007-2008 and the L15A7 1.5L I4 iVTEC in 2009. So, your screen snapshot does not apply.

And, this thread is about the Fit, not the K24 in the Accord or any other K-Series engine.

Neither Fit engines utilize oil pressure to maintain tension on the cam chain.

Nice work Power of dreams. That is the drawing I was looking at but couldn't figure out how to print it. I agree the two systems are not the same and the Fit/Jazz has no connection to oil pressure.

knaira112387

chain.

madhatch

agreed. but funny how the fit in the picture has a belt!
and k20 is a civic motor not accord k24 for the accord.. I do like the thought of an oil pressurizes tensoiner though.. but then again i keep good care of my car.

fit second

problem in my car, the engine vtec l15a when I started moving the car before the first gear, the car slowly and gets worse when the pickup on my aircond.Help me please!!!!!!!!!!

Looks like a belt but it's a chain, just doesn't have enough detail in the picture.
