Engine questions before I buy
Hey gang, would appreciate some answers on the VQ37 engine. Guess am paranoid after buying a GTO and finding out it ticks like a 150K-mile old truck. HATE that. Never thought an engine (especially an old bastard with pushrods) with hydraulic lifters would tick when new. They blame it on the aluminum block. None of my many DOHC V8 engines have made a sound like that, but am ready to have my first V6 car (thanks to fuel costs, and their superior performance).
Anyway, on to the questions:
- Does the 3.7 have chain or belt-driven cams?
- Does it have hydraulic or mechanical valve actuators?
- Does the engine is supposed to audibly tick at idle? I don't mind engine noise as long as it's not the 'tack tack tack'
- Does it have variable valve timing on the exhaust or not? Brochure only mentions both variable valve timing AND valve lift on intake, but nothing on the exhaust.
- Premium or regular fuel? I'm afraid it'd be premium, but just want to make sure.
Thank you folks. Have a great day.

Thanks man. And the GTO requires premium as well (10.9 compression), so doesn't cough. Runs like a beast, and drives really nice, but can't stand the ticking at idle. Last pushrod engine I EVER buy, and last domestic (and any subsidiary) as well. This car looks like a European car inside (that's why I traded my Vette for this), you can see GM's hand (not a good thing) all over. Much rather have less power but more refinement. I'm done with V8s and expensive cars. With something like the G37, it's a waste of money. Thank you for your comments again.

Hey, drove a 6MT this afternoon. Didn't really get on it since it was new, but drives very nicely, and don't see all the criticism of the engine not being smooth; smooth enough for me. However, there was a real downer for me, and it was the damn center console (too low and far back) and door armrest (too low). Didn't enjoy driving with my right arm hanging; HATED that. What the hell was Nissan thinking? Geez. And my left arm wasn't comfortable either. Bummer. Don't know what I'll do, but the fact car is first model year and dealer wants sticker, it's looking doubtful I'd be an Infiniti owner. Will depend on the competition. Will keep you posted.

That's perfectly normal indeed, and I know how that sound like. I'm talking about valvetrain tick. But thanks for making the comment.

And yes, I put the seat all the way down, and felt too low. Didn't adjust it up while test driving it (was a short one), but I'd certainly do that if I owned it, leaving the armrests practically useless. I'd need to drive the car again, but don't know how dealer would take that. HATE to feel pressured, but there's no other dealer around for 300 miles. That's one thing I like about Lexus; they always turned me loose on their cars, and alone. Even before I bought my first. After the 4th I could take it home if I wanted to (I didn't). Thanks again; appreciate it.
