Hello gents,

Got a question for you guys. Does anyone know the torque specs for the head bolts and valve cover for the 4G63T?

I have no idea where my manual is and couldn't find it when I searched. My new head gasket (metal cometic) just came in and I need to fix it ASAP!

**Side note: Has anyone ever seen a head gasket just leak oil right behind the exhause manifold? not burning coolant,not running hot, good oil pressure, good compression and everything, still runs/idles fine, just hemmorages oil from behind the exhaust mani. I thought it was wierd, i know the 420a has a common problem with it leaking from the corners under the intake mani, but never heard of this in a 4g63.**

I've heard of the valve cover puking before.

i've never really noticed anything like that except from where EMC said, the valve cover gasket.

If the head gasket is stock it's probably a better idea to replace it anyway. the valve cover bolts should be torqued to 14ft.lbs and I will check my manual when I get home for the head bolt spec unless someone beats me to it :thumbsup:

i recall the head bolts being 55 lbs of torque but dont quote me on that. cant find my haynes manual or i would check. if ic an find it ill post it when i do.

The manual says the torque sequence is:

Step 1: 58 ft/lbs
Step 2: Loosen completely
Step 3: 15 ft/lbs
Step 4: tighten 1/4 turn
Step 5: Tighten another 1/4 turn

front of engine ->
7 5 2 4 10
9 3 1 6 8

Now I dont know about everyone else but that seems kind of odd that you would loosen the bolts completely during a torque sequence.

if its apr then its about 80-90 /w there lube, w/o its about 100

when u go to loosen u have to do it in backwards order

so the last step is tighten to 58 lbs if u are loosening? that makes no sense >.> lol

no first u tighten it to 58lbs the fully loosen them in backwards order then tighten them to 15lbs then 1/4 turn in sequence and again 1/4 turn in sequence

Yeah, i would call that a tad wierd. But hey, if it works, it works. I was going to go ARP, but I really don't need it.

If I do any upgrades, it will probably not be any bigger than a T28. FWD DD, so I really don't need any more than that. I just went with the Cometic matal because I didn't want to change it again.... ever, haha.

felpro head gaskets are where its at. only ones that dont leak on a 1.8T build :D

Thank you gents for all your help.

Head is back on, new gates racing kevlar timing and balance shaft belt, new water pump, and all new timing, balance shaft idler/tensioner pullys replaced. Royal purple oil and K&N oil filter.

RUNS BETTER THAN EVER!

One problem though. 14 ft lbs cannot possibly be the right spec for the valve cover bolts. It mashed the gasket really hard, broke the head off of one of the bolts and cracked my volve cover. Thank god for jb weld, it should hold until I get another one.

Speaking of which, does anyone have a volve cover lying around?

thought they were 7

Ok this might sound weird to but the Haynes manual says 30 in/lbs which when calculated to ft/lbs comes out to about 2.5. How you measure 2.5 ft/lbs is beyond me.

i usally just get them nice n snug by hand

I've also heard just finger tight.

Yeah well, got some bad info from someone...

***cough...cough...peewee....cough...cough***

I thought it sounded wierd, should have just went with my gut instinct and just tightened them down snug. Ultimately my fault. At least the head bolt torque was right, that's a bit more important.

yea the head bolts y more important just remember next time nice n snug lol

14ftlbs is for the oil pan. 30 inlbs is for the valve cover like wayne said, or snug. You really can't measure 2.5ftlbs you have to use inlbs or newtons if you have a 3/8 torque wrench.

pwee that is for the gst man lol its the right order and steps lookin at the book now i can take a pic to show ya lol
