I would just like to start off by saying that any insight or help is greatly appreciated. So I've got two issues and the first being the oil pressure switch. I believe this to be the source of a major oil leak on the backside of my B18B1. I'm just wondering the tools that are required to reach it and the diffuculty of changing it. The second is a valve cover gasket sealing properly. I've purchased a new valve cover that is cleaned but what is the best way to clean the gasket area on the actual head? I want the best seal possible so this motor will actually keep some oil in it. Thanks very much for any help!

 

Bueller... Bueller... Anyone? l0l!

 

for the valve cover gasket, I've always used a straight razor to scrape off whatever is left on the head ( being careful not to get debris into the inside of the head), as far as the oil pressure sensor, i've changed quite a few and usually just the open end of a box wrench. If I remember correctly its a 19mm.

 

Is it possible that the major leak at the back of your motor is the rear main seal? I only ask because I know people who have had similar major oil leak problems in the past, and that was the cause.

 

I'm not sure how you figured out that these were the source of you oil leak.

So, I'll blame your leak on the brand of oil filter that you are using.

The rubber gasket/seal on an oil filter varies from brand to brand.
For instance the brand Wix, has a short seal and shouldn't be tightened up as much as the oem filter.

Take the filers out of their boxes and look at the height of the seals, for yourself.

 

for the valve cover, clean the head surface thoroughly using a razor, then a rag and brake clean. dab a small amount of silicon only in the corners of the cam arches. install the seal into the valve cover, then install the valve cover

 

Thanks very much!

The oil is dripping directly behind the motor and onto the exhaust. I believe I would have major clutch slippage issues with a rear main seal leak as well... I don't currently have that issue *knocks on wood*

I did not know that and is terrific info dude! I will definitely check that out too!

Thanks very much!

 

I use scotchbrite pads and paint thinner to remove the last bits of RTV sealant.

I think it's a 25mm deep socket for the oil pressure sending unit. You unplug the single wire and boot first.

Clean the threads and apply a little but of RTV sealant on the threads. Thread back in by hand and tighten the sending unit enough to seal the tapered threads. Avoid over tightening or you'll strip the threads or crack the block. It's almost too easy to do it with a 1/2" drive since it doesn't give a lot of feedback.

My daily driven integra I had was leaking from the same spot. It's an easy fix as long as you don't break antthing.
