timing question and top end rebiuld

[black91idi]

finishing up a top end rebiuld heads were completly gone threw with sterlite valves with upgraded springs, new prechambers and cnc valve job with new arp stud kit for the 7.3 idi, my problem is that in the rebiuld i pulled my ip tower off to fix a leak and replace freeze plug, i took mulitple picturs of the orientation of the timing gear, i got it all back together and running, once running it runs really strong smoke is dark not white, my concern is if the ip timing is off a tooth would that cause the slow starting or would alil air in the system cause that, i know there is still some bleeding to be done once running it takes throtle great smokes a tiny bit on start then clears up to normal, the only other thing i did was turn the fuel screw up almost one flat

Did you take the IP off the gear before you took the tower off, and put it back on? Otherwise your really just relying on luck to get it back on perfect. That said, you're starting so that's a good sign.

Yes you could be a tooth off, the only thing that's going to tell you for sure, is getting your hands on a meter. Gary "Icanfixall" runs a meter rental program, and is an awesome resource for all things timing related.

If you still have air in the system, that will defiantly give you problems starting. Also, do you have a pyro? Turning up the fuel can get you in trouble real quick.

took the tower off in one unit with gear in thinking it would be easier to get back, i took about 8 pics of were it was timing wise and got it back to were it looked like it was from the head one imageand tried one tooth each way and the way it is now is what seemed to match up to what it was, pyro is going in very very soon, fuel turned up about 1/2-3/4 flat, im looking into doing a turbo set up with new injectors and ip, before i started the engine would never get to 3000 rpm and would typicly start breaking up around 2400-2500, now it hits the rev limiter with no breaking up at all, intested in the meter rental

FYI, these engines will run with the timing out 180 degrees. Hard starts and black smoke.

 

[Wyreth]

Well, you may have gotten lucky. There are little Y looking marks on the IP gear, and the timing gear that match up. If you pull the IP off the tower, then lift the tower, you can use an inspection mirror to see in and match up the Y's.

as far as turning up the fuel. N/A's run hotter EGT's than a turbo, so turning up the fuel without a pyro is SERIOUSLY asking for trouble. Personally I would turn it back down until I got a pyro installed. You've got alot of work into that engine to risk burning it down.

as for the meter, PM Icanfixall, he will get you set up.

i read that on here, i used the dowl pin for the timing mark, its not hard like turning over for a minute more like cranks a few times before catching, im thinking its more of an air in the lines problem just in the back of my head that i might have a small timing issue

If it sounds like a powerstroke timings off if it's more smooth it's better. you may need glow plugs or a fews not makin good connection. the smoke if it's not blue at idle. the timings probley ok and any more smoke is from the ip being turned up. don't run it hard go to parts store an egt gauge drive it home and install gauge I bet the air will work its way out in about 5 miles then drive like you stole with your egt gauge and see where your at. I bet it's somthing simple you did all that hard work and took note your probley safe but do get a meter and time it but I think it's simple stupid lil things

 

[black91idi]

Thats the thing, it sounds tighter but with so many veriables im haveing a hard time pinpionting what it is, the thing that made me tear it down was a leaky head gasket, i dont thing it was leaking compretion but when running you could see it pulsating and dripping oil from it so i pulled it apart and noti ed i had some hair line cracks in the precups and some leaky valve seals and worn exhaust valve giudes, so i had the heads rebiult new prechambers, sterltie exauhgst valves, turbo valve springs with all seat preasures checked and the even flow benched it and.checked.spring rates at lift, decked and the new arp stud kit for the 7.3 idi with copper spray around the edges and oil and water passages, heads are torgued to 130 arp says 125, return lines and caps, orings and injector seals, as for how it sounds its close to a cold start but not at loud, runs smooth as can be exept for a few misses from air

Too late to mention this now, but I'll put it here for future searches. When taking the gear tower off consider doing this... take the fuel screw access door off the passenger side of the pump, and rotate the engine until the fuel screw appears. Insert the correct allen wrench in the hole, and leave it there. This then becomes your method of ensuring the pump shaft/gear do not move, and you have the correct orientation when you reinstall. Naturally, you will want to prevent the crank from moving also.

Yah its one of those "why didnt i do this" times, while your here if you dont mind im interested in new injectors and pump and curious on the prices, while i had the engine apart i noticed i had one BB code injector and a few other odd ones, im gona trt n save up for new ones and do a custom turbo setup

 

[Agnem]

Sure. Just shoot me a PM.

 

[black91idi]

Im thinking of running an hx35 turbo any thoughts

 

[black91idi]

ok so hears the deal, i got home from work had a few beers started the truck once it started thought it did sound alil power strokey so had one of the ***** moments and pulled the ip tower up enough to turn the gear the direction i thought if it is off it should go so i turned it one tooth counter clock wise hopeing its gona work hit the key fired right up no smoke and sounded nice n smooth so it was off one tooth the whole time

 

[Devon Harley]

lol a lil dose of liquid courage will never hurt anything. also helps give the best of ideas lol. glad shes runnin good its always the simplist thing and as far and the hx35 i think thats a good choice they spool quickly. still want have alot up top if thats what your looking. i think it would be plenty please put it under the hood i think its better. IMO for me the only way as i off road mine from time to time

With a Hx35 it will spool really well. Hairyboxnoogle has one on his and it works extremely well for him. I think you will like the performance it adds and the really good spool it provides.

Another question I do have is, you mentioned having upgraded valve springs, what ones did you use? Comp 910's?
