vvteye Posted July 30, 2006 Share Posted July 30, 2006 Quick history: See the link in my sig for the car in question but I bought it in February on 90,000 mles. In March it had a full service including flushing and change of oil. After 2500 miles and on return from my fortnights holiday in June (giving the oil time to set????) the enine sounded rough and it was missing. I will admit to driving it for another fortnight albeit on any boost the engine was even less responsive than on an inch of pedal. (I now assume the occasional sudden degradation would be down to sticking valves). So off to the garage. On examination with MkIV Suprastore compression was lost in 5 and reduced in 4. On opening the engine they found what I would descibe as a coalmine!. The result of this was a number of bent, loose valves, and so on. (I assume Martin will fill us in on more technical details if questions arise!!!) The lower block may be able to get away with honing a couple of cylinders and the pistons are ok. The bottom line is that the engine needs a total rebuild and will end up costing around £3,500. Now I am over the cost shock at least I will be getting back a T plated VVTI with 0 miles on the clock. So... are there lessons to be learnt. Is this the result of poor oil change routine, the lack of a turbo timer etc? Anyone with a history on this car? It lived most of it's life in Plymouth. And before you all suggest it.... I can't afford to go Single at this moment in time and can't afford to upgrade the pistons either unless I am forced (or persuaded)!

LeeT Posted July 30, 2006 Share Posted July 30, 2006 i've never seen one that clogged up before So what does martin think caused this? Quote Link to comment Share on other sites More sharing options...
vvteye Posted July 30, 2006 Author Share Posted July 30, 2006 i've never seen one that clogged up before So what does martin think caused this? Neither he or his team had ever seen one as bad. I think he puts it down to a history of lack of oil changes (crap service history). I'm wondering if this is what happens if you don't let the engine cool down after hammering it. The car is BPU but there was no turbo timer! Martin? Quote Link to comment Share on other sites More sharing options...
Scooter Posted July 30, 2006 Share Posted July 30, 2006 have you or can you get a picture of inside the oil filler cap? I'd like to see how bad this area looks on a engine thats this clogged up this bad, as it may help me and others when looking for one.......

Pig Posted July 30, 2006 Share Posted July 30, 2006 ouch, having similar prob. cant decide what to do with the rebuild at the moment. will be interested to see if you uprate the internals! Quote Link to comment Share on other sites More sharing options...

I'd like to see how bad this area looks on a engine thats this clogged up this bad, as it may help me and others when looking for one....... Martin took tyhe picture. I looked at the filler cap to see if it was head gasket and as far as I recall it looked fine. Even the oil on the dipstick looked reasonably clear!

Rayman Posted July 30, 2006 Share Posted July 30, 2006 Interesting thread, sorry to hear about your problems, anyone have any idea what have caused it for sure? Quote Link to comment Share on other sites More sharing options...
vvteye Posted July 30, 2006 Author Share Posted July 30, 2006 ouch, having similar prob. cant decide what to do with the rebuild at the moment. will be interested to see if you uprate the internals! I am upgrading the bolts butnever predict wanting more than 500 BHP so will hold back on the pistons if I don't end up needing a rebore. If this is the case then I will uprate them but that's an extra £550 +. One more thing... the oil strainer was completely caked except for about 15%. MArtin said this would seriously reduce the oil flow and cause major localised overheating. Quote Link to comment Share on other sites More sharing options...
Scooter Posted July 30, 2006 Share Posted July 30, 2006 wonder why toyota went for a strainer arrangement and not a simple pickup pipe? Anyway for those that are curious you can see one part of this area on your own car. If you remove your filler cap look to the right and shine a light down and you'll see the level of deposits......... Quote Link to comment Share on other sites More sharing options...

If you remove your filler cap look to the right and shine a light down and you'll see the level of deposits......... great advice i was gonna ask can i check this...cause i dont want that happening!! say someone spots a lot of build up, will one of those oil flushs help remove this build up, the type where you run engine for 15mins at 2000rpm then drain. (though you may have to do 3 or so flushes for that amount!!) Quote Link to comment Share on other sites More sharing options...
Daston Posted July 30, 2006 Share Posted July 30, 2006 ouch thats not good! Tottaly off topic but what is that devise in the first pic thats holding the engine? And how much are they? Quote Link to comment Share on other sites More sharing options...
i-macca Posted July 30, 2006 Share Posted July 30, 2006 It's just an engine stand, about 40-50 quid from places like Screwfix Direct, Machine Mart etc. Quote Link to comment Share on other sites More sharing options...

bondango Posted July 30, 2006 Share Posted July 30, 2006 HOLY COAL MINE!! never seen anything that bad in me life!!! Build up on Cam bearing caps and valley is probably from localised over heating due to poor oil and maybe coolant contamination, what condition was the crank and oil strainer in??? also, was the compression down to sticking valves or maybe slight HG leak on coolant allowing small oil/coolant contamination..martin???

hadyn Posted July 30, 2006 Share Posted July 30, 2006 Looks like its had very very few oil changes in its life. Quote Link to comment Share on other sites More sharing options...
grahamc Posted July 30, 2006 Share Posted July 30, 2006 My fear is that mine looks pretty much like that... will see soon when mine goes in for its build. Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted July 30, 2006 Share Posted July 30, 2006 Sorry to see that. What was the service history like?? Did it have any?! Quote Link to comment Share on other sites More sharing options...
JohnA Posted July 30, 2006 Share Posted July 30, 2006 I've seen some pretty neglected and abused engines in my time. ...but this one wins by a margin. What did they run it on FFS, lard? I'd be tempted to forgo this engine and use it only for spare parts. I wouldn't trust a single bearing out of that mess. Cronenberg would be proud to use it in his films.

CardiffSupra Posted July 30, 2006 Share Posted July 30, 2006 Bloody hell mate did'nt know the car was in that mess, Looks so nice and tidy from the outside. Good luck with it fella. You can have your wheels back this week mate, sell them and you got a little bit of cash to start with.... *Cough* Single...... Quote Link to comment Share on other sites More sharing options...
vvteye Posted July 30, 2006 Author Share Posted July 30, 2006 Sorry to see that. What was the service history like?? Did it have any?! It had a a full service in January 2005 then done 8000 miles before I bought it (or so I was told - given a 3 month warrantyfrom torque imports). No paperwork at all and torque were reluctant to ever give me access to the previous owner or service garage preferring to act as intermediary...

vvteye Posted July 30, 2006 Author Share Posted July 30, 2006 *Cough* Single...... That's what the missus is threatening I'll be!!! With the BPU as it stands Martin is suggesting I'll see 400+ bhp when it's completed and as it leaves only another £20K of components to go wrong it'll be like having a brand new car!

chilli Posted July 30, 2006 Share Posted July 30, 2006 wow, i've never seen anything like that before! maybe it was run for a long time on a cheap mineral oil? maybe it serously overheated one time and cooked the oil in there? do you know what the oil pressure was?
