HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Poly engine mounts melted

Post  Arthropraxis on Sun Feb 04, 2018 2:20 pm

I have been noticing some new vibrations, noises and general harshness to the car recently. Finally started looking around and found my drivers side poly mount has melted. The steering shaft is touching a header primary and the oil pan on the passenger side is touching the steering rack (manual rack). I think this has been going on for a while. I have been driving this car daily for around 6 years.

Is it worth it to upgrade to the new style mounts? I noticed on TPC website they have solid bushings for the mounts as an extra, what are the normal bushings made from?

Has anyone used both new and old style mounts that can give some feedback on pro's/con's.

Thanks, for any feedback. If someone has a set for sale contact me.

The solid bushings will give you the same feel you are getting now. The poly bushings dampen some of the vibrations and noise. Check with Kent at TPC. I think he has better bushings now.

So, the bushings in the new style mounts are poly. No issues with them melting like my old style mounts have?

Melted?! I thought polyurethane was a thermoset.

The mounts I use currently are from energy suspension and are rough. Id like to go to 4 inch thick silicone rubber. Laughing Laughing

Deformed, not dripping plastic. I would guess the heat from the headers made it soft and then deformed.

I had to us my cigar lighter to burn the plastic away from the upper two nuts to get a socket on them.

No, they were from TPC, I bought them around 2009, that is why I said "old style" in the original post. If this one fails I may upgrade ,or not, I can buy 5 of these inserts for the cost of new style mounts.

I forgot they did that in the beginning. The mounts you have are made by energy suspension. They are late 60's Chevrolet motor mounts. I buy them from Summit Racing.

Honestly, if they lasted several years, I would replace with the same thing you already have. Like you said, they can be replaced several times for the cost of upgrading.

I replaced it yesterday. Feels much better now. It looks like the upright may have been twisted so I made sure everything was sitting happy before I tightened the bolts.
