dangerous brain Posted May 1, 2004 Share Posted May 1, 2004 Originally posted by Steve Cargill Is that how you stopped the failures? BTW is FADEC working properly these days, I've not heard of anything bad for a while? You don't really stop the failures but you can put them off and more appropriately safely predict when they are likely to happen. When you know how close to failure you can safely take things you have the peace of mind to run a component a lot longer than you might otherwise. RE the FADEC no its still a piece of sh*t IMHO. I used to work the engine test bed as well and its horrifying how many DECU's (digital engine control units) came into us with faults that we were unable to reproduce. We had one come in off an aircraft that plummeted 30 feet in landing phase and wiped out the back legs of the aircraft. It behaved normally with any other engine but match it back with the engine that was on the aircraft at the time (we got the engine in shortly after for post heavy landing tests) and any time you demanded max power increase from lower power levels it spun the engine down to idle before picking back up. The engine didn't do that with any other DECU either Scary huh!! Neil there are more bits to go wrong in a piston engine than a gas turbine!!

Is this a big deal or not? I'm not sure but there can't be many parts of the engine that spin at 10,000+ rpm, if any. So a clingy oil might just not be a good thing. Only guessing now. I've also heard a turbo dealer say that it's not good stuff, I think he said "magnaslop" not my words, I guess he would know refurbing them all the time.

Scooter Posted May 1, 2004 Share Posted May 1, 2004 i hear you Tim, it's typical really, i remember seeing the ads from Magnatec and the theory behind it seemed good, but all along it seems i'd have been just as well (if not better) off with Halfords own 10-40W! best use one of the other suggested 'regular' oils for the TT me thinks........... BTW i accept the genuine comments from people in the know, it just seems strange that with the amount of enthusiasts on here (and other turbo car forums) that this isn't common knowledge if the problem is a potentially serious one............

Timwildman Posted May 1, 2004 Share Posted May 1, 2004 I dont know if the stuff is actually magnetic, but if it is or has the same effect, all of the magnetic particles in the oil (i.e. worn engine surfaces) would collect in the smallest clearance parts of the engine. I know in older turbo cars Ren 5's etc they can have problems with oil supply to the turbo. The old oil supply pipes gather all the old shitty oil. This causes a lack of oil to the turbo and failures. The man who does the turbo's also suggests that on the older cars fitting a bigger diameter pipe. I guess as prevention measure.

dangerous brain Posted May 2, 2004 Share Posted May 2, 2004 All in all though a damn good drain and flush through every say 30,000 miles with regular oil changes ie every 3000 like i do mine should offset any problems on the lubrication side. Nearly all modern oils are the dogs whatnots in comparison to oils of days gone by. Bearing in mind now that some manufacturers are seriously upping their servicing intervals should speak a bit for modern lubrication technology. If you are worried about wear rates in things tedeco make all sorts of threaded mag plugs that could easily be inserted into oil systems. Pop one into your turbos oil return line and periodically monitor it. If you get a significant rise in ferrous debris on the plug then you can take investigative/corrective action before you get the death whine!

Supra ST Myster Posted May 3, 2004 Share Posted May 3, 2004 So is there a good oil then for worn seals so it doesnt leak through as much?? if so which one? Quote Link to comment Share on other sites More sharing options...
Alex Posted May 4, 2004 Share Posted May 4, 2004 Terry, wasn't ignoring you, just have no Internet at home ATM... My info was the same as Tim's and yes it's word of mouth...but sometimes the telephone does come in useful That wideband unit looks pretty sweet...have you used it?

Guest Terry S Posted May 4, 2004 Share Posted May 4, 2004 Thanks Alex. I wonder if the comments were for the 15-40 or the later 10-40. The wide band, I have a few friends that seem to like it. Must say it has some great features. It's the kind of thing TRL should be building. I will stick with my Autronic B analyser. It seems far superior to the Motec PLM some tuners use. Not cheap mind.

Guest Terry S Posted May 7, 2004 Share Posted May 7, 2004 knowing the problem the Supra has with the FMS I wouldn't risk a cheap filter, you have no idea how well it filtrates of what impact it has on pressure. Go to Mr Toyota and get a Lexus 4 litre one. Quote Link to comment Share on other sites More sharing options...
Barry Posted May 7, 2004 Share Posted May 7, 2004 I just got me some Valvoline fully synth and a TRD filter. This is gonna be one busy weekend!!! Oil, filter and plugs on the Supra. Rebuild the R5's engine (currently has no pistons and liners in it!) Adjust the valve clearances on the wifes Clio, and fix some annoying rattle down near the front wheel. And on top of that I've got the take the sister in law to Ikea to get a load of stuff for her new flat and watch the footy all day sunday!

paul mac Posted May 7, 2004 Share Posted May 7, 2004 on the subject of the lexus filters, i've been using these for ages but recently could'nt be arsed with the 30 mile drive to go and stock up on em so got a halfords i checked the oil a few days later and it was black whereas the oil using the lexus filters is still pretty clean about a month later,so they must be doin something right, when you compare the filters side by side the lexus is quality and the halfords is £4, no contest, i've also got a mate who found some metal swarf actually in the top of a halfords !, i would'nt touch em with a barge poll Quote Link to comment Share on other sites More sharing options...

dangerous brain Posted May 7, 2004 Share Posted May 7, 2004 It was only £4 for the filter run it til you get another one. The money you saved on the sythetic oil £30 should more than make up for that!!! Quote Link to comment Share on other sites More sharing options...
mr keef Posted May 8, 2004 Share Posted May 8, 2004 Yea but im gona have to drain the oil so im gona need oil and a filter:conf: Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted May 8, 2004 Share Posted May 8, 2004 Can you not swap the oil filters over pronto stylee that way you don't lose much oil. And thinking about it the filter is higher than the oil level in the sump isn't it so you should be able to swap it out easily enough. Just a bit messy. Not nearly as messy as a mate of mine that received 25 litres of hot transmission oil on his head when a filter he was changing in a chinook helicopters fwd xmsn self closing mechanism didnt close and he couldnt get the filter back in for love nor money lol!!!

SUPRA FLY Posted May 10, 2004 Author Share Posted May 10, 2004 Ok guys since there seemed to be some confusion on which oil to use I contacted Jemca. Their view is that use of fully synthetic oil (zero viscosity) on older cars i.e. around 10 years old will make them smoke a lot. They recommend the use of semi-synthetic oil like Shell Helix Plus 10W 40 or something similar on older Supras. Newer supras can take Shell Helix Ultra which is fully synthetic. Am having an oil filter and oil change done this weekend was thinkin of using their recomendation unless I get STOP from someone on the forum.

I would think that would be due to the zero viscosity rather than the fact that it's synthetic. You can get fully synth oils with a higher viscosity than that (i.e. Valvoline 5w50).

TRD3000GT Posted May 11, 2004 Share Posted May 11, 2004 Any kind of lexus filter I should be using? Which filters are hands down the best?

Alex Posted May 11, 2004 Share Posted May 11, 2004 Hmm I thought there were problems with using the 4L V8's filter on the 2JZ - worth a search on SF. Quote Link to comment Share on other sites More sharing options...
mr keef Posted May 11, 2004 Share Posted May 11, 2004 Im sure u can get magnetic filters now so any bits of unwanted metal debris is dealt with better,i think u can get em of ebay,a freind told me about them yesterday.worth a look. Quote Link to comment Share on other sites More sharing options...
