Willie. Posted December 4, 2008 Share Posted December 4, 2008 only routed to the inlet plenum for the sake of emissions Really? putting the holes in a different location categorically does not resolve the problem Really? So if there was no top plate at all, and the oil could quickly get down into the individual chambers etc...would this not change things? So surely a different top plate would be better. The oil needs to get below the plate quicker than it currently does. That means the holes don't work correctly, so I disagree with you.

I.Mupferit Posted December 4, 2008 Share Posted December 4, 2008 Willie, I am not going to launch into a lengthy diatribe here about the positioning of the holes in the plate. I am speaking from personal experience with 3 of my own engines and 2 others I have seen and discussed at great length with the owners, one of whom has forgotten more about Duratecs than most will ever know. If you choose to disagree with me and them, that is your prerogative. I am merely stating known facts, not hearsay or supposition. Yes, if the plate is removed, you have a different set of circumstances prevailing. That much is obvious. I understood we were discussing the notion of siting the same holes elsewhere and my reply is based on that premise alone - not adding holes or removing the plate altogether. As for the crankcase breather pipe, why else would it be routed to the inlet plenum? Brent (aka Arfur Nayo) Toyota power It's the future! Link to comment Share on other sites More sharing options...
John Vine Posted December 4, 2008 Author Share Posted December 4, 2008 The ultimate 'fix' is easy enough as Millwoods suggested in the first place, ie, fitting a dry sump. But that is costly and I can well understand John's desire to keep the cost down, especially if he just does the odd track day here and there.There is absolutely no point him spending 100's of pounds trying to fix a very minor problem when it can be easily and cheaply circumvented by the suggested method of re-routing the crankcase breather. Well expressed, Brent. That is exactly my situation. Having spoken again to CC Parts (thanks, mic, for the info ), I've ordered a camcover breather hose, hose connector, catchtank elbow (all standard R400D bits), plus a couple of blanking caps. So, I now have the choice of (a) re-routing the crankcase breather to the catchtank and blanking off the plenum input tube, or (b) blanking off both the crankcase breather and the plenum input tube. I'm favouring (a) at the moment as I can monitor oil loss (if any) and, if the sump is indeed overfilled, the surplus should be expelled. Tony (TLG): Yes, I'll certainly report back on the fix I end up applying. JV Edited to correct my mangled quotes!

Stuart Faulds Posted December 4, 2008 Share Posted December 4, 2008 John, solution (a) works fine - our track R400 has been run like this for a year and a half now. Link to comment Share on other sites More sharing options...

Willie. Posted December 4, 2008 Share Posted December 4, 2008 Brent, for an engineer you don't do much engineering. I'm sure a man of your ability could recommend an easy and cheap fix to the Raceline sump. Willie Link to comment Share on other sites More sharing options...
mic Posted December 4, 2008 Share Posted December 4, 2008 The easy fix is removing the pipe from the plenum. As Stuart says , it is a tried and tested fix. Why try to make it harder. Link to comment Share on other sites More sharing options...
I.Mupferit Posted December 4, 2008 Share Posted December 4, 2008 Willie, I am bored with this now and have said all I am going to say on the matter. Your attempts at winding me up are not going to work, ok? Subject matter closed now as far as I am concerned! Brent (aka Arfur Nayo) Toyota power It's the future!

John Vine Posted December 8, 2008 Author Share Posted December 8, 2008 An update... I've now re-routed the breather. For those contemplating the same mod, these are the parts you need: 38E074A - breather hose (R400D camcover, with L-elbow) -- expensive, and about 50cm too long! A026E0322Z - rubber elbow (for catchtank) 70208 - hose connector B7048 - blanking capCost of parts: £46.35And here's what to do: Remove the existing rubber breather hose (crankcase to plenum) Attach the L-end of new breather hose to the crankcase breather outlet (using one of the existing size-25 hose clips) Drill a 19mm hole in the top of the catchtank (opposite the existing hole for the camcover breather hose) Insert the rubber elbow, trim the breather hose to length, and join the two with the connector (rubber lubricant helps here) Secure the hose with cable ties Fit the blanking cap to the plenum input pipe, and secure with the other size-25 hose clip (rubber lubricant helps here too)Alternatively, if you plan simply to blank off the crankcase breather, all you need is two of the blanking caps.JV(Edited 31Dec18 to correct P/N for rubber elbow and fix formatting) Link to comment Share on other sites More sharing options...
TJG Posted December 9, 2008 Share Posted December 9, 2008 John, thanks for information. I spoke to parts last week and neither they or the chief engineer was aware of the problem or any update I have now ordered parts. Link to comment Share on other sites More sharing options...
John Vine Posted December 9, 2008 Author Share Posted December 9, 2008 You're welcome, Tony. I've some pics of the installation so blatmail me if you'd like them.(Edited 14 April 2019:)(Re-edited 14 March 2023: link to photos. Why does Photobucket keep messing up links?)JV Link to comment Share on other sites More sharing options...
