View Full Version : Lowered car - Clearance.

Dropped the girl sunday, then yesterday I notice oil leaking out. I had my other e30 lowered with the same setup for over a year without issue, 1 day and this?

I raised the car and it looks like something impacted the drain bolt, so I pull the plug - using a spare bolt to hold the oil in. The sealing ring was broken so I replaced it and tightened it back on.

Oil still dripped.

I let all the oil out, and inspected the inside threads of the pan. About 2 or 3 crack lines.... Great.

I made an aluminum plate with a 5/8" hole for the bolt, like a big washer, loaded the bolt with jb weld and bolted it on to patch the hole. I have 3 spare pans anyways, just don't wanna get into that now.

Here is my idea, I'm thinking of putting a spacer plates under the engine mounts, maybe 6mm - 8mm thick (aluminum). This should raise the pan off the ground an equal amount. I don't think this should have any negative effect on the operation of the car, but 6mm higher from the ground will make me feel a little more comfortable when I'm driving.

By the way, I haven't seen any oil dripping all day. :cool:

you might wanna make sure the fan isnt touching the rad since the fan wont be parallel anymore with the rad. Ive heard stories of broken mounts causing the fan to rub up against the rad, this could be the opposite situation.

For the pan, I would change it asap since the pan is actually cracked, plus, you have a few kicking around anyways.

How much is it dropped by>

do the volvo mount swap (2 right side volvo240 mounts w/ alignment tilt cut off. saw this on e30tech a while ago. part number# 274111. years 76-93 they are suppose to give you a bit more clearence without screwing with hoses or the fan blade. can anyone confirm my findings?

someone on another site was making skid plates that went from the fron cross member to the sub frame. I am thinking of trying to get one myself

Yeah, I'd get a skid plate... guy on r3v makes them himself, you can get a steel one shipped to the toronto area for around $230 or so... probably worth it if your car is low enough to make this a consistent problem. Might be a better option that raising the pan higher... you might throw something else out of whack.

i might be able to make some skid plates, CNC or laser cut. I talked to my guy and he said he'll make a sample for me. If its all good, I can make some more for you guys. I can even get it either powder coated or galvinized. Ill let you guys know soon

I'm just pricing out how much material is gunna be which depends on the size, grade and gauge the metal is gunna be.

We have the same problem with my brothers 318is, the pan sits soooo low! Is there someone who manufactures somekind of pan that is flatter or allows more clearance somehow?

Next year I'm prob. gonna do an s50 swap, does the pan on the s/m50 sit a little higher at least?

Otherwise it will be a skidplate i guess! Please keep us posted iignite.

Stainless for the skid plate would be best. It's stronger and therefore could be made of a slightly thinner material, no rust so no need to powder coat.

Of course cost and design functionality are key.

I can get stainless, but I'll need to find out how much it is per sheet. At work now so I cant really check anything atm. Ill find out the prices vs material later on

It actually sits super low on E30s..you might shiat yourself when you see it. With my old m50e30 on IE's and stock basketweaves there were a few light scratches on the pan from booting around the shitty streets.

Good thing with the m42 pan is its a 2-piece which makes it SUPER easy to change if it breaks.*wave*

i guess it'll be a skid plate....

I made some spacers from some spring pads, the thick ones 'upper rear'. I cut the cone section out of the center and punched 3 holes in each. I placed them between the upper strut mount and the strut tower. I think the car is up maybe 4-5mm, it looks better too. This is the easiest way that I can think of to make a small adjustment.

I'll see how the rubber holds out, that stuff is really tuff, and since it's sandwiched in there really nice and flat, I'm sure that it will last quite a while. Failing those I suppose a larger aluminum spacer could be fabbed up to accomplish the same thing, I wouldn't suggest more than say 5mm, unless you change the studs (longer) on the strut mounts.

lol richie, i might need a person to mock up an M42 skid plate, interested?
