Hi Everyone,
It’s been a long time, but I finally found time to tear into my 87 300D to fix exhaust leaks at the manifold where the tube fits and another at the turbocharger. I’ve got it all tore down and parts arriving Thursday. I found the mixing pipe, air crossover pipe and intake manifold caked with sludge almost 1/4 inch thick in places. Cleaned the mixing pipe and dropped the other 2 pieces at the shop where they are being tanked. It is my opinion that this buildup has to be restricting airflow. Any thoughts? (I am already planning to block the EGR)
Now I need to decide if I should spend $300 to have the turbo gone thru. It turns smooth and quiet and we were having no performance problems with just over 100K. The car gets driven only about 7K a year, half city, half highway. I know the trap was replaced by a previous owner, but I don’t know about the turbo. We plan on about 5 more years out of the car, and I am leaning toward putting it back in without the rebuild. Any thoughts on this?
Thanks, Brian
