Hey guys,

The head bolt job got approved by my local dealer and i just had a few questions.

Is there anything i can do while the motor is apart other than long tubes ?

What should i be expecting and or looking for?

Any advice or input is appreciated.

Thanks,

 

The headbolts are getting done under warranty? :O

 

Cam follower replacement is standard part of the job. If they weren't going to, have them use the M159 followers. They're straight replacements and a better design. Insist, even if you have to pay for the parts. Also, make sure they check for cam lobe wear.

 

Did one fail?
Did you have a cel and coolant loss re: the sib?
What year? Are you under the original or cpo warranty?
They are doing under warranty and upon request?

 

Not under warranty but getting my head bolts issue fix.
What is Cam follower?

 

So you are paying for it?
Did they fail?
Is MB doing it goodwill?
Details please

Cam followers are the buckets between the cam and valve

 

+1... NEED details

 

coolant and Oil mixing when checking the dip stick repair being done at local shop, OEM parts are about 800.00 and labor 1500 to 2g's

replacing heads gasket stud bolts and other little things.

installing shorty header while i'm in there.

 

Are any bolts broken?

 

heads and bolts coming out monday or so.

 

Let us know if any are broken
Or if they break while being removed
Also take some close up pics broken or not
Thnx

 

will do.

 

Use the m159 valve buckets and arp head studs! You'll be good to! Forget the shorty headers. Waste of money.

 

After i take a look at the VB i'll make a decision then, If they look good they stay.
Shorty header already got them from a member here for a nice price.
After looking at the factory manifold anything in better, arp head stud are over priced so im leaning to the new OEM stock bolt for now still up in the air.

Also once you run 1000 mile or so on ARP studs you'll suppost to go back in and retorque them.
factory studs are one time use, set them and for get them.

 

False economy on the buckets! Stock are a bad design and cause tappet noise and cam lobe wear. The new parts are cheap at twice the price.

 

I have no problem with the revised oem bolt
I would definitely use the revised m159 buckets while you're in there
My 2 cents

 

Yes under cpo

Deff will do!

loss of coolant, terrible idle and engine surging at times. 09 bought it with 17k about a year and half ago now has 45k

way to hijack


I was thinking of using the weistec oil/air seperator, but i want to see how the intake looks when out first. Will deff have my guy check for cam wear.

 

Interesting thread, definitely following. For sure the pictures of the removed head bolts will be a plus, seen some nasty ones on here aleady from that same issue.

 

How did they confirm a bolt broke?
Any cel's
Did they do the any tests?
Bubbles in the coolant?
Coolant in the cylinders?
Etc

Let us know if they find a broken bolt and post the invoice if you don't mind

 

Looks like they are pulling engine and tranny out the front, wonder why not just lift engine straight up and out.

 

Isn't it easier to remove the engine/tranny as an assembly?

 

I had the tranny dropped in 40 mins.

Removing all those hoses and rads in the front is a huge pain.

 

Why do you think they're pulling the engine if they're just working on the heads?

 

Might be easier and a better job since they are doing headers too
Much easier to work on an exposed engine

 

Does anyone think replacing motor mounts at the same time might not be a bad idea?
