Knowing there are a lot of guys out here that have put some serious miles on their engines, has anybody seen any issues with the intake manifold gaskets? Every engine I have worked on has not had any problem, and I have not had a case where I needed to replace the intake gaskets. They have always popped off without issue. But.. most of the engines have not had more than 50-60k miles on them.

I have loved them over having to scrape the heads on my older SBC's.


Cross posting this to ls1-tech as well.

 

i wouldnt even think of changing the gaskets.

 

i would replace them

 

I take my intake off regularly... i reuse the gasket without any leaks

 

never had any leaks reusing the stock gaskets imo

 

What kind of mileage did you have on your engine(s)

 

I took my intake off 2 times with the 5.3... it had 110,000 miles

 

...and no nasty RTV to worry about...just snug 'em down and go!
