Well time for my next issue...engine rattle
Hi All,
Looking over to you guys before i start to fix or put more money and time into this g.
A couple days ago i started to hear the following around 2-2500 rpm mark, i've parked the car until i figure out next steps.
From my research it 'might' be the timing chain tensioner...thoughts?
cheers!

I don't want to be the harbinger of doom but that sounds a LOT like rod knock. If in fact that's the issue your motor's toast. I can't think of any other engine problem that sounds like rod knock.

In my experience it usually starts out quietly then gets progressively louder the more the motor's run.

well i called around and can dump another ~1500$ into this for a motor with 90k kms, or cut my losses and try and find something else.
Sad...i was starting to get all the other lil gremlins out of it, and starting to enjoy it.

ya apparently thats all in...
if i go this route, i'd want to look at the timing chain and components while the motor is out.
also thinking of going a different car - lexus IS series or BMW 3 series. Just not sure i want to drop even more money.

Fix the G, they're good cars. Don't mean to step on anyone's toes but I'd avoid a BMW like the plague unless you have deep pockets and like working on cars.
Nothing more expensive than a cheap BMW. My son got a free 323 from his future father in law, within 6 weeks he was putting in a new motor because the head gasket went and it wasn't that much more to put in a lower mileage (by a lot!) engine vs fixing the head gasket. A month later the transmission cooler lines broke. Window regulator failed on a 9 degree morning and left the driver's window stuck down. Trim pieces were cracking (saw that the other day on a 2011 535 I was detailing...all the plastic at the base of the windshield was cracked), just one thing after another. My brother owns a 2008 E93 335. That's gone once the extended warranty is up even though he loves the car. He's seen how much the warranty has already save him.

quick update for those following this...
Motor is in, running good!
Couple things i noticed:
* heat in the cabin doesn't get as hot as it used to (maybe thermostat)
* on start up after a few seconds i see some whitish smoke coming out, it seems to go away after some time (i'm monitoring coolant levels).
It feels really weird to not hear the start-up timing chain rattle lol

The heat issue is more than likely air still trapped in the cooling system. You've probably read on here that our cars are notoriously hard to bleed all the air out on a coolant change. Squeeze, carefully, both the upper and lower radiator hoses when the engine's up to temp. They should both be firm and hot, also make sure you use the bleed plastic screw on the back passenger side of the motor to check for any residual air as well.
