Cameron brought us his Grand Prix GTP that had been running quite rough in hopes that an intake manifold gasket replacement might fix his concern.

We had advised to do a diagnosis beforehand but he was persistent on the gasket replacement prior to any additional work.

We replaced the gaskets and the vehicle had shown no change.

From there, we were approved to do diagnostic work of which a compression test was #1 on our list to get done first based off how it was running.

5 out of 6 cylinders showed good results. Unfortunately, cylinder #4 spark plug gap was found completely closed and the compression results were very sad.

Mitsubishi Monday!

Tyler's Lancer Ralliart got towed in due to it dying on him and not restarting.

We found the culprit to be a failed alternator.

We got the alternator replaced and his Lancer back on the road!

Subaru Saturday!

Jesse brought us his STI for an installation of Goodridge stainless steel brake lines.

He had also noticed a small drop of brake fluid when the car was sitting that was found to be a rotting line in the rear

We were able to cut that line on the inside and create new lines to correct that leak along with the install of the lines.
