Baffling a 4age sump, any do's and don't's?

[~SlideWays~]

Never had it done before, but need to do for my club car (fwd ae92 turbo).

Are there any sort of designs I could follow or just do something simple?

My starlet Gt has a factory baffled sump , I have a spare sump you can have a look at if you want .

As to what is the right or wrong way to baffle a sump there are many experts/opinions on the subject. However basically all ou want to do is drian the oil away from the crank as fast as you can & then try & trap it in the bottom around the pickup as best you can so that there is always oil around the pickup even under hard acceleration/conrering so it can't suck air.

Unfortunately I'm not at the workshop & at present I don't have a FWD baffled sump lying round to my knowledge, so I can't suuply any photos. But basically all I've ever done is if neccessary make up a crankshaft scraper plate than runs close to the crank without touching it to try & help flick off any excess oil on the crank & also is any splashes up hopefully it won't go on the crank. Then if you look at the actually sump itself I normally make up a baffle plate or two that goes in just below the line of the bottom of the crankshaft at BDC, I try & space these plates so there is a bit of a gap up the side & where they overlay to allow oil to drain through or previously I have cut louvres into them for this as well. This basically helps to trap the oil in the bottom of the sump. What you do for a pickup & in the bottom of the sump is up to you, some people do bugger all & have a swinging/sliding pickup, others use the standard pickup but build a box around it with trapdoors to let oil in but not out etc, I wish I had a sump off a motor to take some photo's of but don't at present.

I'm not too sure who could help you down your way, but perhap try to find someone with a race-car that's running slicks or has had oil starvation & has modified there sump & see if you can get some pics/idea from there. I have at times used sumps from Hi-Energy in OZ & modified them to suit as some of there sumps are alright straight out of the box, don't they'd have something that'd fit as they mainly do v8 stuff, but there may be some photyos on there site.

There is a couple of photos of a rwd 4cylinder ford sump on this page to give you an idea of the what I was talking about above http://homepages.ihug.co.nz/~homewood/Fabrication1.htm
FWD will be a little different as the engine sits the other way etc but it gives you some idea.

4age has a plate like that already. may be possible to improve on that part of it though.

I was just giving some general ideas on baffling a sump. You'll possibly find you have to remove the standard setup in a 4age & ame a new one or modify it to do something with the piuckup anyway. I forgot to mention above that I'll generally try & make any baffle plates bolt in so you take them out to clean the sump properly.

Thanks atmosports, some useful info there. I'm going to have a search for some pictures on google.

Got to also find someone able to weld oil saturated metal!

Found some interesting pics of different ideas:

I didn't think the "wings" would be vertical, I thought they would be horizontal around the edges.















Combination on of both types I've found.
