Ok so people say that a block guard prevents good cooling on the top of the cylinder, well what if I installed it 1/2" from the top of the deck? would it be possible to do this seeing there is alot of room to work with, if it can be done then it would solve the heating issue and still reinforce the upper portion of the cylinders.

Let me know what you think.

They suggest installing them 1/2" below deck, so that won't cure any of the common problems.

I will never use a blockguard ever again. I think they are ---- and a waist of money. Are your internals built? If not, I would worry about those first because they will be the first to fall apart. The sleeves are stronger than most people think.

I'm sure you've already decided to buy a blockguard and there is nothing I can say to change your mind, but I wish I could. Good luck with it.

no no, I might post my block, havent decided yet, its gonna be a built D16Z6 forged internals, and I need to handle alot of boost, so I'm thinking of I buy a block guard and get it put in further down, it would still do its job and still allow coolant to circle around the top of the cylinder and allow maximal cooling where needed.

I don't think mine is causing any overheating problems.
My car has been overheating lately, but I don't think it is the blockguards fault because it didn't overheat for at least 2 months after installing it. I think I have another problem but i didn't get to diagnose it yet.

I've seen a lot of cilinders crack with a block guard installed..
I think because it's of a different aluminum...it expands and shrinks different from the block it self, causing stress on the block and cilinders and making it crack.

the fact that you take away coolant from the top of the cyl wall means it will get hotter there and cause detonation/pre-ignition.

if you are fully comitted to a reliable built motor, sleeve it.
