Way to much smoke!!

To be honest though I have to say that I can't see when they designed this head that they didn't take the swirl into consideration. They had to of.
 
We are almost sold out right now with a lot of good performance feedback. I suggest tuning and verifying cam centerline, timing, lash, etc.

I know you want to call it the heads fault, but everthing is not identical. You have a .020" over head gasket, which I have seen cause exactly what you are seeing. Also to dial everything in exactly with what you had before you needed to check your injector protrusion into the cylinder, and then match it with our head factoring for the .020" over gasket. Do this and run the same gasket thickness as before, and verify piston protrusion before and after, and then your statement that everything is identical except for the hamilton parts would be much more accurate.



Our heads move air, a lot more air. I have written numerous times that just bolting it on and thinking you are going to increase 150hp is not logical. As much as people in the diesel community hate to go about things in a logical manner, the scientific method is the only way to verify identify your issue. You just change 10 variables and said that you only changed two.

You need to address these issues.

Cam centerline
lash
piston protrusion before and after
head gasket thickness before and after
Injector depth before and after
injection pump timing before and after

And before you bash me online, try calling me.

If you are unable or unwilling to verify all of the things listed, I would rather give you a refund than be forced to prove the issue is not with my head.


The .020" headgasket is my guess, Bigger ports with less compression, considerably lower port velocity and will make engines lazy down low. Add to that, with less squeeze in the cylinder efficiency drops considerably.

I don't recall bashing you at all. As a matter of fact my last post said " I find it hard to believe that when this head was designed you didn't take Swirl into consideration" I said that cuz everyone is sayin that swirl is the problem in the other thread.
 
I went with a 20 over gasket in hopes that I would be safer than a stock gasket since I didn't want fly cut pistons. With the 188/220 cam that is.
 
I appreciate your business and would have been more than happy to walk you through any one of the steps in your build to make sure you got exactly what you wanted. I hate that you might have to do some more work on your engine to get it how you want it. A phone call could have saved you a lot of work.
 
Well I didn't think i would have had a problem I thought it would work just fine or I would have called lol. When I posted this earlier I didn't think to call you because I didn't think your cam or head where the problem. I just figured I throw it on here to see if anyone had anything useful to say. If anyone else ever had this problem and it could be an easy fix. But back to the 20 over gasket and way it was before and after. The block was decked which also took away some so the 20 over really wouldn't be 20 over what it was before cuz the block is now slightly lower. Correct?

I knew this would bite me in rear lol. What that really means is I don't have time to type a lot right now and seems that putting this head on has some how cause a problem that if I just reused the old head I probably wouldn't have right now. But $3600 is a lot for a head. However I am still hopeful it is worth it.

well how much is the block decked? if you went with a 20 over gasket and you only decked the block 5 or 10 the you have moved the injectors 10-15 thousandths away from the piston which would cause smoke issues. and you have also changed the compression ratio of the cylinders.
 
That all is part of the questions that need to be answered. What was piston protrusion before and after. Piston protrusion before with standard headgasket, vs. piston protrusion now with the .020" gasket. And, if you did not use the exact same pistons, then you cannot assume that they are the same. Aftermarket pistons many times are .010" or more shorter to allow for block machining which could compound the issue of a thicker headgasket.

And as far as Joes comment. I will gladly skip TS and fly up. If its my fault, I will work and fix it all for free, including air fare. If it is, a setup, tuning issue, low compression issue, or if your chargers are maxed out not allowing you any more power, you can foot the bill.

See this is what I was looking to hear earlier. really I was looking to hear put thinner washer in and good to go, just cuz thats a lot less work, but either way.
 
well a thinner washer will drop the injectors but that depends on the decking of the block, the head gasket thickness, pistons. the other issue is the fact about the reduction in the cylinder compression ratio.
 
My truck is set up very similarly but I used a stock thickness gasket and the thinnest washers on my injectors. I also have quite a bit more fuel and turbo. The truck is slightly more smokey than it was before but I went to 5x20's and a maxed pump. This is with a gt4202 single (75/82 1.01). I can drive in traffic fine with out smoking to bad givin the setup but it did haze black before I played with the afc some. I have seen .20 over gaskets cause more harm than good but almost used one for clearance as well. I noticed the biggest change in smoke was related to dv's pump had full cuts which are nasty, swaped in some 191's which were not much better, then some 181's which work pretty good, didn't have any 131's to try or I would have. I hope this rambling is making sense.
 
sorry to hear about simlar issues.. i hope you get it figured out.
i think after this weekend i might try some thicker injector washers to see if it helps with mine even thow i didnt really think i would having the injectors around .040 deaper than before..
 
Im still confused as to all this. It makes sence with the thicker gasket, more space, less compression, ect, But Adam had 60 taken off his head then used the 20 gasket, and a stock gasket I believe. With the same results. If anything even if his pistons were shorter than the stock ones he was still closer than the stock setup seeing as he had 60 off head. Correct?
