i had a block gaurd in my old z6 greddy setup 18X,XXX miles. I dropped it in and bolted the head back on and ran it for 10,XXX+ miles with no problems. I plan on using it again in my next build. I don't consider it better than sleeves, but I do think it is better than nothing.

I have never had a problem with them, and if you install them correctly I think they are beneficial.

 

I don't care who hasn't had any problems, that means nothing. I am more concerned about the people that have had problems, and there are plenty of those. If it aint broke, don't fix it...

apparently there ARE plenty of those eh? They are just all missing this thread?

Where are all the people with ruined blocks/engines due to blockguards?! Lets hear some horror stories!

 

Dude I'm not going to hold your hand, just search and you will find them. There a a million threads on block guards.

Oh and like I pointed out earlier in this thread "RyanCivic2000" had a block guard and he had head gasket issues (d-series). And a few people were telling me block guards were to keep the sleeves from shifting, well obviosuly in his case the block guard did nothing to help that.

If your motor is going to blow a block guard isn't going to save it. It your car detonates enough to crack a sleeve and block guard isn't going to save it. Tuning will save your sleeves from cracking and your block from blowing.

uhh, why would it? they arent made to remedy HG issues...i dont think sleeve shifting is his real issue, cause if it WAS then the BG would have fixed his problem.

Secondly, i find it hard to believe there are "plenty" of people who have problems with them. I say this becuase there have been a decent number of replies to this post, many of which come from people who actually use a blockguard, and none fo them cite problems with one.

Yeah and i searched, although there is lots of talk about how they can cause problems, i failed to find on post that was actually someone who said: "I used a blockguard and it caused these problems, the problems went away after i removed the guard".

But apparently you HAVE found these posts so please, share some links...

 

So it's not to keep the sleeves from shifting? A few others in this thread seem to think that's what they are for. Looks like you guys with block guards say they are used for different reasons. So why do you have a block guard again?

Here's another good thread on sleeves... http://forums.evans-tuning.com/viewtopic.php?t=133

Detonation and very high cylinder pressure cracks sleeves, right?. If you can explain how a little peice of aluminum will stop your car from detoanting or stop the extreme cylinder pressures, then let's hear it.

All that said... tune your car and you will be fine.

Wouldn't it help reinforce the top of the sleeve where it sees the most pressure, where a crack is most likely to start forming?

translation: block guard stops sleeve shifting

maybe the order of the words confused you?

Whoever said that my sleeves shifting were the cause of my headgasket blowing?

 

I never said that was the direct cause of your headgasket issues. I was replying to "splitime" because he said he installed the block guard to deal with the sleeve movement and head gasket issues. I was just pointing out that you had headgasket issues with a block guard, so it obviously doesn't help with that issue. I just don't see how a block guard helps at all, it's normal for the sleeves to move, but as long as your car is tuned well it they shouldn't crack.

Yes, but if there are headgasket problems from shifting sleeves a blockguard would help. In my situation I believe the headgasket problems were a result of too much timing. So really your example is irrelevant.

Yah, I think we are mostly all on the same page. Im not worried about cracking issues, but headgasket sealing issues.

And if Ryan's was timing based, then it would be more of a head "lifting" issue wouldn't it?

I just want stability for the sleeves, im not worrying about cracking them. If I detonate that badly.. im sure other stuff will go first

 

bottom line is blockguard increases the stability at the top of the sleeve.

Sometimes this can cause hotspots, but thus far i have not seen any evidence of it causing hotspots to the point of damage.

 

kinda off subject but, beerbongskickass, if that is a pic of yourself in your avatar you are one ugly ****

 

I used to run a blockguard, no problems and would do it again if I didn't have the $$$ for sleeves.. Do not weld them in, should naturally settle approx 1/4 below deck height.
