6.5l injection timing

Word: ARP's stuff is krap, likely what's in there now, and leaks.

Blue threadlocker works. I have had it in since 2011, 60K+ miles, heads off several times for not head gasket problems, pounded a worm clamp into a head... Others suggested it before me, but, 2 engines later under the worst abuse and hot rodding... Until something better comes along blue or red works, period.

They used permatex thread sealer in it. My next issue is am i going to get the passenger side head off cause one stud is close to firewall? Ima have to install studs with heads on only hand tight maybe a snug to insure they are seated now with the blue lock tite do i cover all the threads or just a small line?

 

[Trucker2k16]

The company used permatex tgread sealer with tiflon

The hang up is, that works in most engines. There is something about these engines that it fails, consistently. Idk why.

Whatever you choose to do threads with, they need to be fully coated liberally.

 

[Trucker2k16]

Yea im trying to figure that out now lol just bummed out they leaking

So I take it the one that's leaking is near the firewall?

No thats on passenger side my leak is ondriver side

 

[ak diesel driver]

no I mean to close to the firewall to pull just the one. If you can get it out I would try resealing just that one, first, before I pulled the head. Hence the guncleaning brush so you can reach down thru the head to clean the threads

No thats not leaking the only one i see leaking is on driver side outside by injectors the 2nd one from the front ima just pull passenger side cover and pressurize tge system to make sure nomore are leaking

 

[Trucker2k16]

Ill end up trying that first once i pressurize the system ill get the gaskets in case it fails then ill do the headache

Do oil samples to check for coolant. This will let you know if another one starts leaking.

How do i do that i pre trip every morning sorry im a truck driver so i check every vehicle i drive lol

You get a kit that your take a sample of the engine oil, put it in a bottle, and send it to a lab. The lab will test the oil, tell you what wear metals are in it, if coolant is present, and how much, if any, diesel fuel.

Some kits have a vampire with a hose the sucks oil out the dipstick. Most pull a sample when changing the oil from the drain plug. In your case checking for coolant can't wait till an oil change. Coolant in oil eats bearings too fast to wait.

I gotcha ima wait till next weekend to go in to it and change the oil with a little luck none under valve cover are leaking

Ok im going into it today now i know its 30 60 90 on torque but i seen some where 100 ft lb with arp assembly lube and 120 with out? When i just checked the torque on the studs i had 120 does that sound right?

 

[ak diesel driver]

Sounds high IIRC arp says 90. I'm going to do mine at 100

 

[Trucker2k16]

Ill probably do mine at 100-110 .410 gauge brush works great not sure about using the cloth to dry em though lol

 

[WarWagon]

The lube used is critical to the torque used. The arp head studs are 130 ftlbs using 30wt oil to lube threads. 100ftlbs with arp moly lube.

Too much torque can rip the threads out of the block not now, but, when hit with 21:1 compression...

What should i do with using blue locktite

 

[WarWagon]

Blue thread locker in block side only. The goal is to seal the stud in the block. Tighten the studs best you can after putting thread locker in. I went overkill and double nutted to get extreme torque on them to tighten the studs, but, all you need is tight so the threadlocker cures. Then use the ARP lube on the nuts - 3 steps to 100 Ft Lbs. If you only have 30 weight oil: 3 steps to 130 Ft Lbs.

You see the new thread where better products to seal studs are coming to our attention.
