Dorman 917-142 Exhaust Manifold Clamp Repair Compatible with Select Models (OE FIX)

Before ordering the Doorman clamp I had gotten some off brand that was half the price.Definitely a case of getting what you pay for, the off brand all most fit but not quite…After fighting with it for an hour, I decided to send it back and just get the Doorman.Once I received the Doorman clamp, I had it installed and the leak fixed in less than 30 minutes.Yes this one cost more but there is a reason; you don’t have much room to work with when doing this repair so you need a clamp that is made to the correct dimensions. Trust me; this job is a PITA; don’t make it even more frustrating trying to save a few bucks.

The clamp was easy to install, didn’t have to trim or move the heat shield on my truck, just unscrewed the dipstick and pulled it aside. I only wish the third clamping bolt was a little shorter, as now it seems it may make it harder to change that spark plug, but I can always remove that one bolt when the time comes if necessary.

Recently started to notice a very audible tick. It wasn’t all the time, but randomly. Sometimes at start up, sometimes while driving, and sometimes never. I inspected from broke bolts, didn’t find any. There was one bolt that had some soot around it (drivers side front), so I figured it was loose. I went to touch it, and it fell off lol. Called some shops, and they quoted $500 - $XXX, depending on how many broke when they removed it.Accidentally came across this when looking for a manifold gaskets. For $30, I’d give it a shot. I can tell it must have been leaking for awhile, because once this was installed and I started it, it sounds like a whole new truck. Well worth the price.HINT: Get the two outside bolts started, then plug in the coolant sensor while the bracket is loose. I snugged everything up, and I couldn’t get the plug to clip, so I had to loosen it all. Drivers side front took 30min install.

Well, you are reading this is probably because your Chevy sounds like a Chevy i.e. the classic header tick tick tick. I stalled this to a 2009 Chevy Silverado 2500 HD but it will fit basically any LS engine (5.3, 6.0, 6.2 etc). Prior to my manifold head bolts sheering off, I did not know this is actually a very common problem for LS engines... Way to go Chevy, have a known problem and still use crap manifold bolts. Its so common that Dorman has this band aid fix to save you hundreds fixing.FIRST, I want to clarify the part numbers and locations to be installed because some of the reviews are misleading. The are 2 different brackets to be used depending on which of your manifold bolt heads sheared off.Dorman 917-107 (looks completely different) - Locations to be installed is for either the drivers side rear or passengers side front.Dorman 917-142 (This product) - Locations to be installed is either the driver side rear or passengers side front.The reason is because the heads are basically the same but rotated 180 degrees. So be sure you get the correct part.Okay, now to the installation. I had BOTH rear manifold bold head sheered off, so I needed both part numbers mentioned above. But this is the installation for the passengers side rear (917-142). If this is the part you are getting you are in luck because its much easier than the 917-107. First step is the heat shield on the manifold is in the way of the bracket from mounting, but its so annoyingly close to fitting. You will have to of around 1/4"-3/8" of the heat shield. I used my compressor cutoff tool that mat quick work of it. A dremel would work well too. I suppose you could try shears, but its in a pretty awkward location. Once the cutting is done it is simply a matter of bolting down the bracket (Used anti seize) and torque to the spec in the instructions. then install the 3rd bolt that holds presses against the manifold (Use high temp loctite) and torque to spec (I think it was 18 lbs-ft).After I completed both sides and started the truck it was significantly better, but I gave and extra one flat turn on the bolt to the manifolds past the recommended torque just to give it a little extra sealing.The whole process took about an hour. Most of it was just figuring out the best way to cut the exhaust heat shield. Once that is cut the bracket goes in in around 10 minutes.Tick tick tick is gone so the brackets do work. The brackets really are more expensive than they should be (around $30), but it sure beats the price of removing the head.Tick tick tick is gone so the brackets do work.

Had a exhaust manifold bolt break and didn't want to risk trying to drill it out. This worked perfectly to hold the manifold in place with no leaks.

Fixed my front driver side manifold leak, I had to plug in the sensor with the wires ran through the hole then bolt it on. I couldn’t plug it in with it bolted on. Quick and easy install and fixed the leak!

Facing the vehicle this works on back left of 06 Silverado 5.3L LM7 / LS3 ( third generation LS engine ). Tightens up exhaust manifold for broken off bolts ( no more leaks ).

It help about 60% got a bit quieter. My leak was on bottom and may have deposits stopping the seal of the leak not sure. But it is stronger made with extra bracing so it wont bend as easy as others you see on line. Dont buy one without the extra support.

Bought for my 2007 Savana 4.8L, 1 bolt broke on each side (rear ones, I also bought the kit 917-107). On a full size van, the rear bolts are super easy to work on. I didn’t had any ticking noise, but only little carbon on the other side. That was more a "while I’m here" job, since I wanted to repair the floor rust. So I can’t say for sure if the kit is working 100%, but it removed the hair thick gap between the manifold and the block/gasket with the proper torque required. On this kit, the bolts are all the same length, the clamping bolt is waayyy too long, resulting in the impossibility to torque it correctly with the torque wrench because of the floor being in the way. Could be easier to install with a shorter bolt, if it was included. Would buy again, but hopefully I won’t need to haha.

Repaired and silenced that very annoying noise issue with my 2004 Yukon exhaust manifold.

15 minutes it took me in driveway! I put it on my 2010 Silverado 4.8 had to bend heat shield a little no biggy. Truck sounded like a POS before, now she sounds like a new one!

Hubby was happy with it.
