I am hoping someone on here can lead me in the right direction.
I have a 78 FJ45 from Canada with a 2F engine. Production date is March 1978. It is smoking like crazy and is fouling the plug in cylinder 5. It doesn't have any smog equipment and the PCV valve is moving freely.
If I clean the plug it runs great until it is fouled again, smoking the whole time. Spark on that cylinder seems consistent with a timing light on that plug wire. On a compression test all cylinders are 125 - 132 and #5 is 130 psi.
I was thinking the first and easiest thing to try is replacing the valve seals on that cylinder. The seals I got from a local Toyota dealer are part# 90913-02033 and is the seal on the right in this picture. When I got one of the springs off the seal on the left with the spring seat built in is what I found. Any ideas why there is such a difference and what should I be looking for?
Also, any other tests or things to look for to try and solve my problem?
Thank you for any help and info.
