Blue Smoke

Okay, I'm gonna go out on a limb a bit Luis, check them PCV's because there ain't no oil on those plugs....#8 we need to see but I kind of doubt it will have anything other than look like a combo of 19 & 12.

Oh, sorry. Luis, I'm Tom!

Also, I know somewhere there is a write up on how to make the heads accept/ use a tapered seat spark plug....I just don't remember where I saw it as when I got my 90 I made up my mind to stick with the cheaper 41-602 plugs.

I just noticed that you have 210 RC's and not the usual 205's. Hummmmm, I'm wondering if they flow too much fuel and the smoke is actually black or slightly black due to the bigger injectors? I have to say this up front, I do not know enough about that stuff to make a call. Lets run down the rest of the stuff first before I have you go off in a fruitless direction.

Are the PCV's readily available?? I think it is time to change mine. Never changed since I bought the Z a few years ago. I also am blowing some blue smoke............

Bob, usually I order the PCV's when I make my "winter maintenance parts order" at one of the online parts houses. I can't rely on the local parts stores for LT5 stuff in my area.

I do them every year, but then I do between 3k to 5k miles a year. I just consider most of what I buy every winter the cost of using my car as much as I can every summer. I hate doing any maintenance during the driving season, so I try to have it all covered before I start my season. I'm like a selfish little kid once the summer starts!

Louis, I really have to say that sizing injectors for a motor, let alone our motors, is waaaaay beyond my knowledge level. I'm still putting my bet on the PCV's....

Do you happen to have a part number and who you order from???
Thanks
