Camshaft Position Sensor Cap O-Ring 1.8

[fixkick]

it's a 1998 Suzuki Sidekick Sport 1.8 / Auto.

There is an oil leak at the back of the head. I am certain it is the Camshaft Position Sensor shaft o-ring seal.  I bought a new one with the Suzuki label for $10.
Marked and removed the housing.  The O-ring that is between the housing and the black plastic sensor cap was installed wrong, is crimped, and is swelled from leaking oil. This O-ring has an o-ring incorporated onto it for the sensor electrical connector.
I have searched high and low for this o-ring, a part number, or anything. Nor can I find the black plastic cap (not that I need one).
I find nothing, not even an online picture.
I am tempted (I typically would never do this) to cut the old o-ring to fit as best as possible, and fill the gap with RTV silicone.
Please tell me there is a source for this o-ring. And share the source.

welcome here.
J18 engine 98. (last one with all mods good)
leaks are never easy to find, unless start clean drive , look, drive ,look , bingo it is here. that is how leaks ROLLs) windage and gravity here are wild.
CMP leaks that is super tricky let me explain.
the CMP on some cars J18 and newer and bigger engines only can be timed with suzuki scan system.
(if the DLC does not have the timing freeze pin bingo this PAIN)
I always match mark the CMP flange to head so later I can put the timing back to where it was AS FOUND.  always do that. using a center punch is best.sharp
J18 engines in 1996-1998 (called Suzuki Sport)  are all on LF (left front) strut.(DLC location)
"test switch" suzuki name is time freeze for using timing light.
jump this:


Color wire for freeze is ,blue-red. seen here

suzuki does not sell parts inside ANY CMP. sensor. just base to head. rear.
there is deep Oring inside that loves to fail and the plastic cap ring is not for oil at all just dust, a dust seal of if oil is found inside the CMP that is the deep inside ring and only that needs to be found

you can buy o-rings as suzuki.
or measure them and by generic rings, metric for top sellers. (miked,(mic'd or micrometer measured) if not a wreck now.
see here for generic rings any size. (viton is best)

to do generic buy 3 sizes, 1 below ,1 at, and 1 oversized. and win, (suzuki does not sell the internal rings)
thickness first then ID.



now I will tell you all I know and have, here,  I will show the base oring Pn. real. first

I have real suzuki full parts lists here, (all markets ) illustrated, (rat holed away for 12 years)
suzuki only sells the whole sensor (means if not discontinued, it is not but is $400 sensor)  sensor+- Suzuki (3310077E20)
and the base o-ring for  Sensor
Ring: @# 33278-77e20
