Anyway to reduce exhaust smoke

[DeanoTS]

What kind of fumes are they?
A cat won't get rid of burned oil fumes

Pretty sure its oil burning fumes

You should monitor your oil usage to get an idea of how many km to a litre of oil.

I ended up doing a DIY valve stem replacement on my 6G74. about 60,000km ago. It still uses no noticeable oil between 10,000km oil changes.
At the time I was far less mechanically capable and though it took me a very long time, in retrospect if you know what you're doing it isn't a particularly hard job.


And yes, the FWD and AWD blocks are slightly different. I believe to accommodate some AWD gear.
But people do install 6G75 motors into AWD cars.

Hi Spetz, does that mean the 3.8 block is the same as the 3.5 AWD block? cheers

They are not.

To fit any 3.5 or 3.8 block into an AWD a small part is ground off the block for transfer case clearance. This happens for all AWD cars
