If one wanted to make a guide bolt (cut head off, new same size metric bolt) to use it for alignment when setting the LIM back on is this possible or all the bolts in at an angle.

Any tricks besides practice for perfect alignment (so drop down is right in place so do have shift and smear rtv out of place at end seal corners).

Thanks.

P.S. right stuff sealant says you only have five minutes work time. Assume that would be until you get the LIM set back on (torque time could go over five minutes, as weight of LIM will do most of the squish).

that is the oddest question ive ever heard. when i did mine i just set it on gently with a friend... it isnt a very lengthy process... and if u bought the upgraded gasket and properly resurfaced everything and got it real clean and used enough rtv... u shouldnt have to do it again. not for a very long time anyway. i dont see the point in a "guide bolt"

I know its not rocket science but was curious as to if any of the bolts are straight, all look angled to me.

What did you watch on the way down, just picked one of the bolt holes and watched it line up I assume.

I just like leaving zero chance for error anytime possible. Can see setting it down a half inch over then trying to scoot it over which would not be a good thing.

i understand what ur saying. but if ur careful when setting it down u will feel it fall into place... once u put the bolts in and finger tight them all and start tightening them in the order ur supposed to... it will seal up nicely. i wouldnt worry too much just be really careful and take ur time ... if u go a couple minutes past 5 min you will be fine

make sure u have new bolts and the updated torque specs for your engine as well... u can find them online. they must be done in a certain order to a specific torque to form a quality seal

Seeing how that's my pic, I can tell you it's easy. Just set it down. If it doesn't line up, pick it up and set it down again. Laughing

I wouldn't try scooting it. You won't get far since the gaskets are rubbery.

Thanks, all.

My understanding is that on the 3800 you can re-use exist bolts. Just clean them and med strength threadlock the two hidden ones so they do not weep oil through the threads?

3400 and think you have to go with new bolts.

No updated torque I have came across, am I missing something.

LIM 11 lbs follow pattern making a few passes to get to final torque

UIM & Throttle Body 89 inch follow pattern making a few passes to get to final torque

Regards. Sorry just studying this to death before I go in, I still would like to see my dam oil sample come back in. Find zero leaks anywhere including coolant elbows but car is definitely doing some sipping, slow and minor but its doing it.

Saberwings, thanks for the pic, I have a number posted to my desktop from multiple sources. Your write up is excellent, glad you to the time. If I go in and do this I owe you.

i would never reuse bolts that were torqued thats how u strip threads or break bolts. u see, when u torque them down they stretch ... u wont get the right torque with old bolts. thats what shade tree mechanics do. besides, they are only like 7 bucks for a set of them/ im not familiar with the 3800. i had a thread going when i did it on my 3400 so i wont be much help in ur project just with the general knowledge i have on doing it with mine. just be glad ur on the 3800 thats a cakewalk i hear. took me damn near 13 hours to do my LIM. heres my thread look what i went through http://www.naioa.com/v2/module.....highlight=

You're thinking of torque to yield bolts. All bolts have a torque value, and most can be reused. It's just when you see a warning about them being torque to yield (abbreviated TTY) bolts that you need to use new ones.

FYI, none of the 3800's LIM or UIM bolts are TTY so they can be reused as often as you like.

Things like OEM rocker bolts, head bolts, crank pulley bolt, etc are TTY and should not be reused.

I've never heard of any problems with the crank pulley bolt. I know its TTY, but really, the "Key" is about 1 inch long. And the belts won't even go on if it's not tightened all the way down.

That's just my 2cents on the the TTY crank bolt.

The Cam has a maybe 1/2" "key", and I don't think the bolt has any chance to let the sprocket off without the chain being off. It might even hit the front cover before it comes out all the way.

The only bolts I'd seriously consider replacing would be the bolts with lots of varying tension and movement. ie. rocker bolts, and head bolts (from the expanding and contracting of the heads vs. block. Also has to hold A LOT compression.
