Long story short, the TB slipped off my VG30E's motor while running at idle.

The rear bank has two cylinders that are down on compression, and one that has none.

Obviously, I need some new valves, but what else needs to be replaced / done?

I know how the internals on an engine are put together / operate, but I have yet to have fix / replace any.

Do I need to replace the valve seats along with the valves? Can you / how do you adjust valves on an overhead cam engine?

Any insight / hints/ tips would be much appreciated. Thanks

 

replace engine. way cheaper/easier. that's what I'd do in your situation.

 

I wouldn't necessarily consider pulling the motor as easy as pulling the head(s). Besides, I have taken extremely good car of my motor over the years, whereas who knows how a donor motor has been treated / how often the oil has been changed?

 

I can't speak to how you've taken care of your motor vs. a junkyard motor, you have a valid point there and it's a significant consideration, but as far as ease of work it's unquestionably easier to yank and replace the motor than to replace the valves on on a VG. This information is from someone who has both rebuilt VGs (and many other motors) and swapped them out many times.

 

Unfortunately, I don't have the required equipment to yank a motor...My plan is to rent a storage unit and do this all with hand tools.

 

You probably will need to replace more than just the valves unless you are pretty lucky. You will be much better off sucking it up and replacing the engine

 

I did the samething to my vg. You need to pull the heads and see if ur pistons r still good. If not then a rebuild is in ur future, otherwise I suggest getting heads from a 97-01 vg33e as it would be cheaper than trying to repair ur old heads. If u go this route, consider getting mild port, valve job plus some cams. Next replace all oil seals, T belt/tensioner, water pump, exh studs and head bolts.

 

VG33.

how did you over rev it... is your rev limiter set way to high? factory is at like 6200.. and damage isn't done until over 7k. I rev mine to 6900 on a regular basis without a problem.

 

I bit too much work and money involved with that...I just want to get it running again.

I have a big-power car, for what that would cost I could have significantly better gains on my LT4.

 

no matter how much money you sink into a Maxima, it's still a nose-heavy FWD car while you have a Vette in the driveway right next to it. As you've said, best solution is to just do a "stock fix" put the play money into the Vette.

That said, when you coming to the track with that thing? I'd love to go flog it a while and show you how it should be driven.

 

Just as soon as you help me get the Max back up and running so I have something to drive after you grenade the 'Vette on the track!

The 'Vette has a fresh clutch, tires, and brakes. Give me a call and we'll set something up...
