Engine mounts

[Try Me]

Re: Engine mounts

You can reuse all the stock hardware. i put a couple extra washers on the long bolts so they didnt come close to the crossover pipe on my atr headers but i could install/remove the engine with the headers/turbo completely installed. If you have a lift its not too big of a job, especially if you feel like dropping the front diff a little, makes it cake...

Re: Engine mounts

i put in my solid mounts today, my polly ones lasted about 10k then melted, I had a fun time getting them out cause they had melted around the bolts and yes they did have the heat shield in also .They go in a lot easer than non solid mounts. I havent started it yet i am still waiting on my converter to get back from TCS to put my tranny back in

Re: Engine mounts

I'll be hucking my in on monday. Hopefully it will be pretty easy with access to a lift and screw jacks!

Re: Engine mounts

Woot! I attempted to throw them in today and failed miserablely! I looked in Alldata today, and it says I should be able to replace my motor mounts in a cake walk 3.8 hours! HAH! BS. I looked at those things. I thought, OK, dropped the front diff alittle. bolts are packed in there. No help. took out the center bolts in the mounts, jacked the engine up. Only was able to get it up about an inch. Could access bolts, but now, rubber is swolen and can't get damn sockets on bolts! ARG! Still don't have access to all the bolts. I only had limited use of the lift at work, so I had to get it done today. Thinking realistically, I just threw it all back together. What's the fastest any of you have replaced both mounts in a truck that's not taken apart?

I just started on mine too this weekend........ This is as far as I got on the driver's side....

I have run into the problem of the front diff. I didn't look much, but how hard is it to drop that down to access the nuts on the other side for the frame mounts?? I've never dropped a diff before in these trucks.

Thanks,

Re: Engine mounts

You can get to all the nuts underneat without needing to drop the diff.

For the drivers side the wrench needs to come from the front bottom corner, remove bottom front bolt 1st, then back bottom bolt, then top bolt. Reinstall in order.

I long wrench will reach all 3 from the front corner.

Pass side is fairly easy compared to drivers side. Again long bolt reaches up.

I just did a set this weekend. Of course engine was out though.

Front corner?? I can only seem to barely even get a finger in the back corner. I remember reading somewhere where some trucks have the diff higher than others for some reason. I have the steering shaft in the way in front of it if my memory serves me correctly.

Looking at the picture, I also have the exhaust in the way. I *might* be able to get the wrench in from the back corner and do it as you describe. I'll give it a shot this weekend.

Thanks :tup:

Re: Engine mounts

*hopes he doesnt have to replace them before (god forbid) I blow my motor*

Honestly, I really do look foward to doing stuff like this. I have no problem spending all day just to get one bolt out. :dunno: I enjoy working on cars that much.

If that's the case you're a simple plane flight away from being able to have all sorts of fun changing mine out for me.

Re: Engine mounts

I think I might try to tackle it again. I might have 3 days available on the rack to get it done in a week or two. I really don't feel like pulling my turbo and and exhaust manifolds out though. Is it even possible to get around this? For you guys that have already done a few of them, how do you go abouts doing it? And how long does it take you?

Re: Engine mounts

did you ever drop the diff? i did mine with the engine out but now the engine is in and the diff is out and i can easily get to all bolts... if i had to.

Wow! Then the Syclone was custom made just for you. I don't know of any other car/truck that I have spent more time on one or two bolts before. Its enough to make you crazy at the time, but it sure is gratifying when it gets done and you put it all back together........and it works. :lol:

I lowered the diffy alittle. I really didn't see much of an advantage with lowering it or removing it completely.

Re: Engine mounts

are you sure you are working on a syty? i can get a friggin socket around the nuts they are so wide open. don't know what else to tell you. my oil pan is gone maybe that is the difference. good luck.

Again, as stated before. Some people have more room than others. Why?? no idea, but some seem to have more room between the frame and the front diff.

what? that's bullshit. these trucks aren't that different. i can see a hole on the frame being off by 1/4" or so but you are talking about magical parts being in the way that his truck has but mine doesnt.

I did mine with manifolds out (for porting the turbo mismatch while I was at it) but I think its doable with them in. I drop the front diff down the inch or so and raised the engine the inch or so.

It took me about 8 hours. The rubber interfered with remove engine block bolts, I think I spent atleast 2 hour fighting with them. The frame bolts also require a helper to hold on the nuts. I even had a hard time getting the engine back down properly on the frame mounts. It just plain and simple sucked, I didn't even need to do mine, I did them as preventative maintenance.

Before you call bullshit......go read up on some past posts. I'm just going from what I've read. Not to mention you say you have all kinds of room.......I can't even fit a finger in there for mine. How do you explain that?? I'm not sure if it was Jeff or not.....but he said that he did another truck a following weekend after doing the first, and the second one had much less room to access the nuts on the backside of the frame. It wouldn't be the first time these trucks throw us a curveball. This is the second one I've owned now. So yes, I'm sure I'm working on a Typhoon.

Just rent a cherry picker that comes apart to lift the engine. Keep a very close eye on the fuel lines when you lift the motor because they may get pinched between the bellhousing and body. If the rubber interferes with the block bolts, just use a propane torch (carefully), and light the fuggers on fire to melt the rubber around the bolts...worked for me. I used a razor or something to cut away the rubber after it was nice and soft. No need to drop the front diff at all, but pulling the heat exchanger, exhaust manifolds, and inner fenders will make life a whole lot easier. Don't forget to loosen up the tranny mount as well so you can get things lined up properly before tightening all of the bolts. The solids don't vibrate much at all...I was pleasantly surprised

Re: Engine mounts

2nd attempt, with all too familiar results! If only I could actually see all the bolts I need to take out! Some of the bolts are half way covered up by that rubber. I'm screwed! Anyone know of anyone experienced in doing these in the Seattle/Tacoma area?

I also called the local GMC dealer too see what they would charge to throw in a new set of rubbers. They said it would be $430 in labor to do. I'm guessing 4.5 hours they would charge me. How in the hell does one do this in 4.5 hours?!?!?!!?
