cleaning ls (maybe paint)

[handyhands]

My motor is mounted, but the cab is not on. How do you guys clean your motors?

[Henry50]

purple power, scrub brush, and pressure washer.

[Jemezcrusher]

Simple Green, brushes and garden hose

I've read that paint can diminish some of the cooling properties of the aluminum in LS engines. I don't know how true this is, but I decided to leave mine bare.

I used all the methods above to clean mine.

Not all LS engines are aluminum blocks. Mine's an LQ4 iron block with aluminum heads.

A true gen IV LS is aluminum. The other L series like the LQ4 and LQ9 are 6.0 iron blocks versions but are not an LS (don't take me wrong the LQ is a great motor, especially since they arent as expensive as the LS and can make the same power) . There was another aluminum block, L76 I think, but had a different ignitions system and different performance.

Oil Eater cleans greasy engine and parts real well rinsed with either a water hose or pressure washer.

I've used Purple power and simple green too. Simple green if you are cleaning it where you might worry about what goes in the ground. I think all three are bio degradable though.

"The basic LS variations use cast iron blocks, while performance editions are all aluminum with cast iron cylinder liners."

Well, I stand corrected. I always referred to the iron blocks as 'Votecs'.

It takes a big man to admit when he's wrong.

its the same way everyone with a truck 4 bolt 350 from the 70s calls it a "corvette motor". technically, they have some of the same parts, and even sometimes the same block casting number, and all the parts interchange, but still a bit of a stretch to call it a corvette mill.

LQ LM LS, who cares? run what you have and be happy about it. You wont catch me calling a LQ an LS, mostly because it already has a two letter designator, but I am just an idiot 50% of the time anyway, nobody listens anyway. that whole family of motors really have tremendous potential
