RE top mounted catch can

Are these used in place of the normal catch can?

Are they any good?

Any one use them?

Nope they are crap. Better off getting one made by LF Performance and fit Mines baffles in the cam covers.

Do it once and do it properly.

Well, I would argue with that. The Autech arrangement is similar to the Nismo oil separator in operation, but its placement gives better head for return flow to the sump. There are other arguments for the arrangement, which was praised in an article in HPI magazine a couple of years ago, but I don't recall the details.

I was convinced of the argument by Danny Fisher, at Imports 101, who understands all of the details. I bought one from Danny and he set it up for me in a two stage arrangement with a "standard" catch can, that I already had fitted - both of which drain back to the sump.

If you want to understand oil flow around the RB26 engine, talk to Danny.

The Mines baffles are good, but fitting a head drain is better.

Cheers.

Thanks - I will give Danny a call to discuss. I was hoping to run the top catch can only?

I was under the impression that it was a alternative to the normal storage type catch can?

I am trying to achieve the best solution against oil surge etc without having to dismantle or remove the engine. At this stage I am looking at keeping 1lt overfill in the sump, having a good breather/catch can arrangement, baffles in cam cover/head drain, oil cooler, and keeping the revs under 7500 when doing a bit of circuit work.

Cheers.

I think baffles are a must and easy to do with the engine in place. The head drain is debatable and there is a massive discussion on the merits of this in the FI section.

I'm a bit sceptical about the merits of that design of catch can as it will only drain back when the engine is not under load. When you are out on the track, if you have engine that breathes a bit, then it's going to get full pretty quickly and pump a load of oil into your intake.

But if Canute has seen a better solution using another catch can along with the JJR one then it might be an option for you. Having two catch cans in the engine bay would give me the shits. Maybe Canute can post up a pic of his engine bay so we can see how it looks.

Here it is. Autech style can is obvious. Second can is on the firewall, next to the ABS unit.

Cheers.
