So I got my lt truck back running and all is well with how it runs but now my fans come on as soon as I crank the truck and ac isnt working. What could of caused that? I already changed coolant temp sensor and thermostat thinking maybe that was it but it is still doing it.

What Deutsch connector kit did you do go with?
I see several on Amazon ranging from $109.00 all the way up to $400.00 so I don't want to buy the cheap one and find out they suck lol.

So unfortunately guys im experiencing another issue with the turbo truck, I took it for a drive last night around town and I keep it around 18 psi on the street. This guy pulls up next to me in a hellcat and I was going around 40 mph, I let him have it, when I put it to the floor it spun a pretty good amount and I let out of it and hit it again and it caught traction that time and I pulled on him pretty good, honestly I thought those cars were faster then that cause I drug him pretty bad. Then after I heard the same tapping noise I heard at the track a few months back then I went in McDonald's and grabbed something to eat because that was my reason for going out, once I got back in the truck and crunk it up the noise was way quieter and by the time I made it home it had gone away.
*Am I experiencing lifter pump up? Melling jb2079 lifters
* Do i not have enough spring pressure?
Cam motion
155 lbs @ 1.780"
380 lbs @ 1.180"
400 lbs @ 1.130"
coil bind @ 1.070"
*cam is 227/234 .600"/.600" 114 LSA 111 ICL
* push rod clearances meassured between 7.2985 - 7.3125 and the lifters call for .040-.080 so im within spec with my 7.375 push rods
-shifting around 7200
*243 heads milled .040 with .051 head gasket
* initially I thought it was the rockers but thags rulled out with the CHE trunnion upgrade

Maybe u pumped the oil out of the sump on that hit, did u check ur oil level….i have a melling hi volume pump on my LSA build and i hear people say that u can pump all the oil out of the sump on a hard hit…..i dunno how much truth is to it or if its just a myth, cause ive yet to pump my 302-2 pan dry….but im just throwing a guess out there….check your oil level, if its on the low side it may be a possibility……what kinda oil pump you running??? If the noise is gone then id just do a top off on the oil if low and maybe add some snake oil of your coice…..i like liquid-moly brand additives , they seem to do well in my vehicles….good luck and hope this helps in some sort of fashon!!!

Snake oil is just a term used back in the old days for stuff that doesnt work……but sometimes it does……..when i say snake oil im reffering to an oil additive or treatmeant of your coice…..I.E., Lucas, mystery oil, stp, Z max, liqui-moly, etc. etc……..like i mentioned before the liqui-moly line up is actually pretty good stuff and has worked for me every time ive used it!!!……..yeah i dont think your pan is getting sucked dry , but who knows….your dip stick will give u a better idea!!! Hopefully you were just a little low on oil!!…..correction you said you oil looked fine so now im kinda stumped…..but like u said if the noise went away then i have no idea where to even start….

my tuner seems to think one of the lifters are getting stuck and then letting back go but fo me I dont understand why that would only happen at wot pulls and then immediately go back to normal. I would think that would be more sporadic. He said he recently built an engine and a brand new Johnson lifter was bad and they had to pull it back apart and change the lifter so being new still doesnt matter. The only thing I would question pm the starvation thing is when it happen I can feel a slight misfire and as the tick goes away so does the mis.

Mm... collapsed lifter will definitely tick but not misfire, pumped up lifter would misfire but not tick . Head scratching for sure, maybe you have 1 or more of each ? Beginning to think that I'm lucky I left my old 2004 lifters in mine when I swapped the cam

I think I may change the oil and put an additives in it and i have 7.375 pushrods in it, but i have 7.4 also. I may try and put those in and see if a little more preload changes anything.
