Sump guards

I will probably need one when the engine change Is complete but I don't know what would work best. Has anyone got any pictures of theirs if your running one.

I have around 3-3 1/2" clearance.

I have 3" under my Dunnell Zetec sump, that has been fine for 11 years now.

I made a flat bottom for the engine bay, with a step down to go under the sump. I have not done a lot of miles, but did go down some very bumpy gravel roads, with no ill effects.

Basically, I used hose clamps to hold the ally sheet to the chassis at the front, and used 2 more clamps wrapped around the chassis behind the sump, with some wood in between the ally and the chassis. Make any sense? It was kind of fun to make actually.

sump

Hi
We made a pair of skids out of 40X5mm steel fitted from the rack plate
Under the sump & back up to a piece of unistrut fitted to the chassis, open end up
with unistrut top hat brackets which are nice & strong galvanised & the
right size to clamp the unistrut to the chassis (no drilling).
Locktite to bolts into channel nuts, nylocks to rackplate.
See rough sketch

Sumpskids

Hope this is clear , or as mud ?
If its the latter give me a utu & I'll send you my No.

This works well ,as there is nothing to hit against, a bit like skids
They Just push the car up. (experience)
Good luck
René

Yes I do and never had a problem because the sump is close to the front wheels and when they go up over a bump so does the sump.

The only issue I have had with the sump was a steel gate stop in the centre of a road with a very noticable camber. It just caught the sump and caused a minor crack. On the way back it was easilly avoided by driving off centre. The crack was sealed with epoxy for 2 years before I got round to getting it welded, never leaked.

At Mallory park there are some viscious speed humps but I have never had an issue with the sump, however, on one occation I crossed one in the wrong place and the bellhousing (which sits about 1/2" below the sump) just caught but with no damage.

An aquintance of mine hit a gate stop similar to the one I hit but there were some differences. His car only had 2" of clearance and he was probably breaking the sound barrier at the time. It moved the engine/box back and up, bent the propshaft, bent the exhaust and bent the chassis. Insurance wrote it off. I had been telling him to raise it since he fitted the 13" wheels instead of the 15" wheels but he thought he knew better.
