I brought my 98 CRV in for an oil change and he strongly suggested I do a
valve adjustment because they tend to tighten up and burn in this engine.
This struck me as strange for a few reasons. I had a 89 civic si and sold it
with 180,000 miles on it. In all that time I think the valves were adjusted
once. It was still running like a clock when I sold it with no apparent signs
of valve trouble. I mention that because I believe the CRV has basically the
same engine. I also thought that valves would only loosen up with time and
wear; not tighten. Is my logic sound or is there some truth to what I was
The 89 Civic is an SOHC engine, and the CRV is a DOHC engine... so comparing
the valve train between the engines is not going to give you the info you
My experience is that in most Honda engines, the intake valves get looser
over time and the exhaust valves get tighter. It just depends what part of
the valve is wearing the most.
I would recommend adjusting that valves whenever the owner's manual suggests
it, unless Honda has release a revised schedule.
Like I said . . . If it's got more than 30,000 miles since the last
adjustment, you've probably got a valve or two that's getting too tight.
I've been happy with the Chilton's manual, which I got from the Honda
dealer. Has a red CR-V on the cover. Did you check to see whether your
CR-V is making that awful noise when you do U-turns as well?
The guy is right. The valves in the first generation CR-V tend to
tighten, and will burn valves. So you should get them adjusted asap,
since you don't know the history. The manual is wrong anyway, but you
should order one from your dealer to save time in front of your
computer. The concensus over at hondasuv.com is 50,000 Km, (30,000
miles)Ask to have them adjusted on the 'loose' side of the spec. The
sticker is under the hood with the specs on it.You don't need a Honda
dealer to do it. . .Just somebody who's good with imports (and the
engine has to be COLD).
Same service interval applies to the Dual Pump Fluid in the rear
differential, otherwise, you'll get an awful grinding / moaning noise
when you turn tight felt-hand U-turns. It may seem to come from the
front of the CR-V, but it's caused by the rear diff. It only takes a
litre, and is a DIY job. Instructions are at hondasuv.com, and other places.
P.S. Go to the original dealer and get them to print out all the
previous service work. They'll do that for you. They want you to be
