California guidelines (https://www.bar.ca.gov/Industry/Engine_Change_Guidelines.html) prohibit the modification of the camshaft that you are contemplating. Consequently, anyone in California who is actually a knowledgeable engine specialist is not going to do this kind of work because it would be flat out illegal....

Hello. The grinding noise is likely an internal transmission issue. Putting the new transmission fluid inside of it likely freed up some already sticking components that were already beyond tolerance ranges and they are now becoming abrasive. I would suggest...

Hi there: Today's OEM parts are made to be cost-effective as opposed to help mechanics fabricate repairs to be honest with you. So, it's probably a good idea to replace the entire housing for a few reasons. First, the thermostat...

This is somewhat normal for this car upon start up unless it is excessive. As to the check engine light, I would suggest not clearing the codes, but rather having the computer scanned by a qualified mechanic from Your Mechanic...

According to the factory repair information, a replacement BCM must be programmed using OEM equipment. It states the vehicle will not start and many other functions will not operate properly until programming has taken place. My advice is to have...

An engine that cranks but doesn't start is lacking one or more of the following: compression, fuel, or spark. You need to check for each of the following to determine the cause. You can check fuel pressure using a dedicated...

A leaking purge valve can cause a hard start and rough running after getting fuel due to vapors flooding the engine out. The shifting problem is most likely not related to the purge valve. This sounds like a shift solenoid...

The 6.0L engine from the 2008 or the 2009 model year G8 will interchange (match: VIN Y, 8th digit, opt L76). To obtain this engine, simply search at Car-Part.com (http://www.car-part.com) and you will find an exact match for your car...

Diagnostic Trouble Code P0008 (https://www.yourmechanic.com/article/p0008-obd-ii-trouble-code-engine-positions-system-performance-bank-1-by-paul-lancette) sets when the engine control module (ECM) detects an out of range variation in the mechanical timing of the crankshaft and the camshaft. The crankshaft and camshaft(s) are normally moving in a fixed position, relative...

Hello. Most likely, the noise you describe is coming from one or both of the camshaft phasers on your engine. These devices which are operated by engine oil pressure, vary camshaft timing (relative to the crankshaft), enhancing engine performance and...

Hi there, thanks for writing in. The oil pan is clear to be removed without lifting the motor. The original pan gasket is riveted to the pan. The new gasket does not need to be riveted on to pan for...

This vehicle uses only one belt and an automatic tensioner.

This could be one...
