Stuck exhaust valve on 98 crv

[laloquera]

1st compression test before valve adjustment.

#1 165 psi
#2 160 psi
#3 165 psi
#4 175 psi

2nd compression test after valve adjustment.

#1 165 psi
#2 170 psi
#3 135 psi
#4 180 psi


This were Im at the moment. If I cant get these valves to sound a bit more silent, I would feel more confidence driving my V.

The B20A3 and B20A5 are the predecessor to the B family. All B-series engines were based from the B20A, but most engine components are not compatible. For more information, refer to the F3-series Honda race car that used a B20A engine. Also see Honda B20A engine.

man sounds like a lot of work
seafoam it!
pull 1/3 can through the air hose that connects to the brake booster
let it sit for about an hour
also put some in your oil
try that

as for cylinder heads you can get a b20 like yours obviously OR b18b with the rounded valve coverpretty sure the heads are the same besides the cams and intake manifold
also a 1.8 head may lower your compression not certain on that one

Illinois Eric. That's a lot info to swallow. I heard the LS integra has a perfect fit.

Yes they also share the B series motor, I think theyre all VTEC though.. so if you can reuse your mounts and the donor's ecu/tcu or the crv's tcu if the donor ecu came from an auto car, it could probably work. even though itll be a hit a remanned head or even sending yours out to be refreshed would probably be the best idea for longevity and simplest. Just grabbing a junkyard head you might have the same issues again down the road. Id probably talk to a machine shop competent in hondas and see what options there are. However a B18C5 powered CRV would be pretty cool
then you also have OBD1 and OBD 2 variances so...

Taking in the CRV into my cuz's shop, hes gonna take a shot at adjusting the valves, if not, we are taking her off and having swap for another crv fully refresh head, for about $200.00 out of Florida. Most shops go this route.

Im back. I think I adjusted my valves. I had to set them at the bare minimum specs on both intake (3") and exhaust (6"). Anyone know if I can go (5") on the intake and keep (6") in the exhaust? My intake are abit on the load side.

Thanks

This job is done deal, was able to adjust my valves within an acceptable range. I also change my oil and added Marvel Mystery Oil. Some old timer swore up and down that It will keep me valve seats and guides nice & lube.
Thanks to all who gave a dam. Peace!
