GT350 Engine Refresh Time!

[Rubyred17]

Happy thanksgiving ya'll!

So I've mentioned that the new motor smoked a bit when cold before. Over the last 2 months, it's been getting a bit worse. Enough to catch my eye and get me thinking.

While I'm working on a heater core bypass between events, I decided to do some digging. I've noticed that it'll also blow a puff of smoke if I let it idle for too long - this indicates valve seals. I originally thought ring gaps because once it got hot, it went away. Today I pulled the intake off and looked into the intake runners and saw that some oil has pooled up on the valves. Definitely bad valve seals IMHO. Fortunately/unfortunately, I'm coming up on the 40 hour maintenance interval for the valve train. Looks like I'll add these to my list for winter maintenance. I'm planning on a full engine removal and investigation this winter, so at least we'll get to dig in and see how the built motor is wearing otherwise.

We are looking forward to a detailed teardown and rebuild- thank you for sharing all you do!

I say you build a spare with the new predator block and Gen 2 heads !

Most welcome!

Damn, I wish. Not in the financial cards. Still need to cage the car and put on coilovers, etc. first

And so it begins!

Will be starting a new thread for this disassembly and refresh since this is a race motor and things will be a bit different.

Will likely get it undressed and on an engine stand tomorrow and start opening it up Friday night.

As promised, there will be full transparency!

How long does it take you to drop the motor and gearbox now?

It's funny. I was making a video of the removal and I claimed I could do it in about an hour and half if I'm focused. Turns out, it's still like 4 due to all the mods I've made - radiator ducting, splitter, exhaust, etc. Sigh. Haha
