Quick question on intake removal

[Smokinyoda]

Anyone know if it is possible to remove the intake manifold without also removing the exhaust manifold on a LDT465? I am replacing my intake and dont really want to mess with taking the exhaust off if I dont have to. TM says to remove them both as a unit, but it has been wrong before so thought I would ask the experts.

Not looking forward to taking those exhaust bolts off...

I'm in the process of doing the same thing. I had to remove the exhaust manifold and top water manifolds in order to get the intake off. I acted like it wanted to come off without removing the exhaust, but the studs were just a hair too long for the intake to clear them. I'm sure you already know this, but the gasket for the intake also seals the exhaust, so if you were planning on replacing it you will have to remove the exhaust anyway. Hope this helps!

I took an intake off to send to another member. I don't remember being able to take it off by itself. Pretty sure they both have to come off.

Thanks for the info, was afraid of that. After twisting and pulling I kinda figured it wasnt gonna come off. Been soaking down the exhaust bolts with kroil, hopefully I don't twist any of them off. The bottom row is going to be fun to get to. Guess Ill go ahead and order that gasket I was hoping I wouldnt need.

I've never twisted a stud off but I've had plenty where the stud unscrewed instead of the nut

Thats reassuring, thanks. So far TNJ is the only one I found who has a gasket set listed. Will call others tomorrow. Hey searls84, where did you buy your gasket?

 

[searls84]

I bought mine from Boyce equipment. They had every gasket i needed in stock. Also, I soaked my exhaust nuts for 2 days before tackling the job. All but the 2 behind the turbo came off super easy! I found that pulling the turbo made removing and reinstalling a whole lot easier. The only snafoo I had was that the 2 rear studs in the turbo broke off. Not a big deal, just took the manifold down to the machine shop and had them remove them. I would also highly recommend having a machine shop deck the exhaust manifold while you have it off, that way you have a completely true surface to mate to your heads. Good luck, and let us know how it goes!

Also, i found the small gaskets for the two water manifolds on top of the heads at the local International semi truckdealership.

Soaking with Kroil is good. Using a 50/50 mix of acetone/automatic transmission fluid is far better. Try it, you'll like it!!!

Part number? Price?

 

[searls84]

Sorry about that...According to the receipt.....
Part# 253660R2
Description 122C Gasket
Price- $1.35 each

I just took the old gaskets in and they matched them right up with ones they carried in stock.

Thank you all who have helped, god I love this place....

Theatrical pause while I grab a beer.

I just pulled mine and I couldn't for the life of me get the intake off with out pulling the exaust. I also had to pull the valve covers to get the water manifolds off. Mine had real still hoses on them, but it was a good excuse to adjust the valves while I was there. Like Clinto said I didn't soak the studs before hand and I didn't have any break except for the turbo bolts. Some of them just screwed out.

I got all my parts from White Owl Equipment in Kinston NC. 252-522-2586 So far they have had every thing I needed, very reasonable on prices, and I've had the parts in 2 days every time I've ordered from them. Good folks all around, NOS parts, and some used stuff too.

Wow your on the other side of the state, I'm less than 2 hrs. from them.

Oh yeah Torque adapters are a lifesaver, buy a good set it makes them easier. Bought mine from Cornwell tools
