For the second time now I have broken the brass 1/8" NPT fitting that is screwed into my block where the oil pressure sensor is located. As with most people I removed my oil pressure sensor, screwed a brass 1/8" NPT nipple fitting and then installed a brass T-fitting so I could screw in both the stock oil pressure sensor and my aftermarket oil pressure sender for my gauge inside my car. I have now broken 2 brass 1/8" NPT fittings causing oil to hemorrhage out of my engine. This is no doubt from vibration on the block and the added weight on the nipple fitting from the T-fitting and stock oil pressure sensor. After the it broke the first time I moved my aftermarket oil pressure sender from the T-fitting to a remote location and used a stainless line to connect it to the T-fitting. Even with this added weight off of the new nipple fitting, that one broke a week later. Not cool! I have on order some steel pieces to be installed in place of the brass ones. They are Earl's fittings, part #'s 961701 for the T-fitting and 901102 for the nipple fitting. I would strongly suggest all Lancers running this setup to switch to steel fittings. Brass fittings are not recommended for installing oil pressure senders and sensors due to their ability to be brittle. Thank god that both times my fittings broke my car was idling in my driveway and not on the highway going 80mph. Just a friendly reminder from the "11psi Kid".

 

Ever thought of trying a oil sandwich between the filter and the block? I know they're used alot (successfully) on Civics, but they're located off the back the back of the block and not at the lowest pt of the block.

Solid motor mounts?

 

I have solid motor mounts all around with the exception of the timing belt side mount. After talking with some hot rod guys this weekend I was told that I should possibly remotely mount both the stock oil pressure sensor and aftermarket oil pressure sender. This way there is only a 1/8" NPT to -3 AN fitting in the block connected to a short stainless line going to the T-fitting. All stress will be off of that fitting. Either this solution or using steel fittings with resolve the issue. Those guys definitely know a thing or two about massive vibration from an engine that will shatter brass fittings. Even the Honda guys use steel fittings when creating a T-fitting on their block for oil feed off of the stock oil pressure sensor. I think us Lancer guys got too hung up on the concept of an inexpensive turbo kit sourced from used Evo parts and Home Depot fittings. Some corners shouldn't be cut. Especially the ones that deal with your engine's oiling system.

 

I have mine on an oil sandwhich adapter and it works well for 6 months plus!

 

^Any problems with your oil fittings?

 

I thought about installing one of those but don't want my oil filter to be positioned any lower than it already is. My car sits pretty low as is and I only run 16" rims.

 

Meh, I have had ZERO issues for a long time and I am low as hell on 17's wita rubber band around em. I have my coils almost ALL the way down.

A little love and teflon tape goes a long way!

 

Run the SS line off the block to a tee then have the two oil press sensors attached to the tee.

 

I thought about that and I still might do that. Right now I've got steel fittings in place all around.
