Seeing as I built this motor when I was 17, there were quite a few things I would have done different had I known better. It appears that I had ported slightly into the oil control ring causing the front oil control rings to wear well past spec. I believe that, combined with using the original (now 120k mile) metal control rings ultimately led to the smoking.

There were other issues I found while I was in there, chattering from the 3mm seals, a dented rotor, and poor side seal clearance on the rear rotor just to name a few. The rusty coolant passages were from years ago when I lived in FL I made the mistake of running the system with little to no coolant.

See the blow by here… this explains why my catch can was filling with fuel!

I have cleaned everything and stacked the parts away on a shelf until I decide what to do. I want to start over with a 2mm motor, and polished stock ports. For now, I am focusing on other projects.

That's pretty good considering the type of miles that your car has seen. What so you think caused the chattering? Hurley, 3mm or what are you using for oil injection? Straight stock or premix in the tank as well?

What are you going to be running for seals in the new motor?

I like stock ports.... they have their place depending on application. The 'vert engine I built was originally supposed to be just a stock engine with a stock turbo making 270rwhp. I didn't change the port timing at all, just cleaned everything up significantly and spent some time in the bowls.

I've since changed my mind and will be doing WM injection, building a mani for it, running either a TO4 something or a BW S360. New power goal is 450. All I'm going to do is crack the keg open and replace the Apex seals... that's it.

This past weekend Mr. Ambrosio (RENESISFD a.k.a "Hard Line Master") came down to lend a hand in bending and flaring hard lines for the entire car. I used 3/8" 316L Stainless along with an assortment of tube nuts and fittings. With John's assistance and his fancy hydraulic flaring tool we were able to complete all the motor lines as well as the under car lines.

VERY sexy...

I maintained the original in series fuel routing. The primary to secondary hard line is my favorite. It fits within a groove in the water pump with thousands of an inch to spare on all sides!

Very sexy indeed.... my only concern would be heating of the SS line in that area being that close to the WP housing. But then again, with the amount of fuel flowing through it, I don't think it will be that much of a problem.....

Luckily, the 3/8" lines were able to fit in the OEM clips and everything bolts up exactly as stock



I picked up the newest 2013 GM flex fuel sensor. This sensor is also made by continental like the others however it is smaller and has improved electronics. "Outputs ethanol concentration and fuel temperature within 250ms after start-up" as opposed by 500ms with the older sensor… not sure how much that matters, but I like that it is smaller.

Been there, done that, more than a few times.... I get quicker each time, but I like it less each time as well

are you going to run any type if surge tank or anything of that nature given how much you track the car?
