I installed a Provent 200 with a 1l catch can on my '94 6.5TD 'K2500 'burb just to keep the oil out of the cold side of the turbo. The Provent with the catch can works Very well, mounted down behind the front axle on the passenger side, and the cold side of the turbo is dry.

Keep up the good work!

glad to see ya here grabowski. welcome to the other side.

Small update.

1: The car has been sitting in the garage since late October for rust repair on 3 out of 4 rear quarter panels and both wheel arches. I'm incapable of finishing the work while weather's too cold for panel bonding adhesive, rust converter and paint. I have other things on the plate, too, so I'm not working on it much if at all right now.

2: Using the Amsoil Heavy Duty 5w40 dropped MPG from a common to 20 to a common 18 even after using fuel additives, removing the roof rack and reinstalling the air dam. This individual 5w40 (which is 15.2 on the hot viscosity scale) did stop oil from blowing past piston rings when I put the car in 1st gear.

3: Amsoil makes a 10w40 that's Diesel compatible and yet it's thinner than their Heavy Duty 5w40 despite looking thicker on the label; it's 14.6 on the hot viscosity scale, a bit thinner than Shell T6 5w40.

Alright, gotta admit something.

I'm not defeated but I've had this car mothballed in the garage for wheel arch and quarter panel replacements on the passenger side. I need a recommendation for making a new inner wheel arch (That is, I need books and such.) I am dumb and clueless when it comes to metalworking but I have new wheel arches and quarter panels. I'll try all I can to re-coat the metal well once I have the inner wheel arch.

Sounds like a great excuse to make experiences with fiberglass and weight reduction

I am a bit confused by the question, you have a replacement quarter panel and outer wheel arch, but you don't have a replacement inner wheel arch? (Correct?)

If so, the technical thing you need to make the compound curve is an english wheel and/or planishing hammer. Youtube and practice pieces can substitute for books. I assume you have a welder and angle grinder to be attempting this.

However as GMT400 prices are at an all time low, you can probably get someone who is parting a rust free one out to let you cut out those pieces for cheap. Or you can drag home a spare GMT400 Suburban for under $1000 (with bad engine/trans.).

Mine hasn't been getting driven as much either, the family isn't thrilled with it as it is loud and warm because the interior and sound deadening isn't completed, and I am not working on that yet because I want to modify the body first. Got to love projects!
