Ok, so my '91 Lumina (3.1 v6) has not been in the best of moods lately. About three weeks ago I replaced the waterpump, belt, and tensioner. Shorty afterwards, I discovered that the car is still not holding coolant when it started blowing steam out of the front of the radiator while I was sitting in traffic (the car wasn't overheating). Bars leaks didn't fix the leak, and made the coolant look like frappuchino. (Oil is not contaminated, and car isn't showing any other signs of head gasket trouble, BTW).
Yesterday, I fill the radiator and overflow tank with water, and drive normally for about 15 minutes around town. When I get to my friends house, we notice that the car is dumping "frappuchino" all over his driveway, and it's coming from the front/right side of the engine (rear passanger side of the engine bay). I can't tell exactly where the leak is, but I'm fearing that it's a cracked block/head. Not sure what else it could be, but I'll figure that out ASAP, before putting any money up for the following parts:
TGP Plenum w/ IAT
TGP Exhaust Manifolds
TGP Turbo w/ oil lines
TGP Cross Over
TGP Electronic Boost Controler Solenoid (new from dealer)
TGP Downpipe
TGP EGR
TGP Intercooler
TGP Charge Pipes
TGP Coolant Lines
TGP MAP Sensor
TGP Injectors
Extra Oil Pan to tap for oil
Complete Engine Gasket Set
& a Few other things I'm sure I'm forgeting
Will throw in a spare 3.1 liter v6 to lucky buyer
$500 or best reasonable offer
(TGP = Turbo Grand Prix, 3.1L McLaren Turbo motor offered in 89 and 90).
The spare 3.1 runs, not sure of the condition other than that. I've also been thinking about doing a 5 speed swap to replace the 3 speed auto that I currently have, and figure this would be a good time.
Now, the camaro is almost finished, and with the daily driver aparently dying, I've gotten some motivation and started to work on it again. I would not attempt to build a turbo motor for my daily driver before the camaro is on the road.
I just wanted to know if anyone is familier with the 3.1 and may know what to look for as far as the current problem. Also what do you think of the plans if the current motor is about to die?
Looking for any input besides the usual "You're lazy and this project wouldn't be done for 3 years..."
