Another Great car leaving this week. Jeff’s 87 Buick Regal T . At the dealer they made it a two tone. So it’s not an original D84 car but it’s a super nice 32k car . Came in with leaks and some older bad work that needed fixing . Rear main, engine pan gasket , valve cover leak . Transmission leaking as well( again do not use a rubber gasket) shifter shaft seal was leaking as well. On the way we decided to replace the stock downpipe with an ugly dump boogered on it . Installed a RJC style Down pipe and test pipe . The heater core wasn’t hooked up so I did assembled the air box , cleaned it out and replaced the heater core. Cleaning up everything on the way. Jeff wanted the intercooler hoses and air intake hoses changed from blue to black . Freshening up everything and making it look much better. Cleaning up the intercooler as well. Thanks for the support!

Busy Busy here👍 , AJ brought his car in couple weeks ago to get some work done. Over the last 5 years we built a motor for the car and a transmission, along with fuel system and more. These cars don’t fair well generally in storage for long time . They definitely tend to wake back up from the slumber with a thing or two to address.

We decided to replace the 40 year old ac system with everything in the engine compartment. Then going in after and replacing the evaporator and heater core & heater valve too. Cleaned everything up and turned out great . Shop was 97 and at idle was in the 58* range .

Also did a new ignition on the car. Coil had corrosion on the coil towers.

Headliner was sagging bad . Got a new one installed / map light. Came out in pieces.

Trans service / inspection and small leak at pan

Car has an aftermarket antenna on the car that didn’t work so we found a nos . To start over and installed. Antenna works great now.

Oil leak by drivers valve cover . Drilled out breather. For more flow etc foam removal

Great car , now off for some paint work .
👍
