happy birthday guys

you may have knocked a sensor or dropped some crud down by the hub off the old shock or out the arch. have you got any brake cleaner? if so spray it down the sensor pick up and visauly check theres nothing there. im not sure if the new shocks would have affected it, never heard it before. more likely just a dirty sensor. try unplugging them aswell and checking the connectors.

a mate of mine already done number 17, to which he carried on running down the road into woolworths and then shortly escorted back out by security with a disapointed face on. ive never seen so many confused faces

i agree with nearly all that, well said. but same, i give up too. i may be a newbee guys and i know im not always right, but i also dont bull about things, not everyone knows everything including me and there would be no parlimant without debate . agree to disagree and move on yer

that is so on a supra i agree. however on some other engines, this isnt the case. ones where the pump runs off the cam belt, ie. some fords, some bmw's etc etc. now days its all off the crank agreed.

We're both software engineers, does that mean we don't know how the Supra engine works? no thats not what i said. i was asking that so i can talk in mechanical terms not in laymens terms. just a comunication question.!

right i think i may have layed that on wrong, my bad if i did, i didnt exactly re read my post. however are you saying that when a cam belt snapps that the oil pressure isnt higher than it should be and cant cause any problems?

good so am i. right what point are we acctualy disagreing over?

no im not saying there are all uncompressed. wherever the cam ends up lying is how the valves will sit. however there not oppening and closing anymore thats why the engine wont run ^^^question asked^^ and no hes not fully right. you guys mechanics?

welcome

theres not much difference between the oem and universal ones apart from slight values, and of course, you have to chop your old plug off to put on the universal ones, but a diagram does come with it for the correct wiring. however never use a universal on anything more than a standard car. ony use oem if you have moddified as they might cause u problems then youll be back to square 1 and buy it all again

yer the SimonB comment is correct but not fully. we clearly have different opinions yes if the belt snapps then the cam lobes do not spin on the lifters or push on the valves, therefore the valve spring is uncompressed so the valve will remain closed against the head. not allowing fuel or oxygen in so no compression combustion or anything. its my fault for defering off the supra engine, ill close up next time

In the internal combustion engine application, the timing belt connects the crankshaft to the camshaft(s), which in turn controls the opening and closing of the engine's valves. It has custom teeth to turn the camshaft(s) synchronized with the crankshaft and is specifically designed for a particular engine. In some engine designs, the timing belt may also be used to drive other engine components such as the water pump and oil pump. so if the belt snapps then these may also be damaged. if a belt snapps noone knows how they react but i know i certainly dip the clutch imediately. if in any case the engines sensors arnt working correctly (ie, not working as the engine isnt running) and the oil is still circulating, this can cause damage to many seals and may harm other components. and NO not all cars have adequate pressure relief valves, nor are they capable of coping with a sudden 100 maybe plus psi of oil pushing around when it only sits at around 30 and lower in idle or cam belt snapped state. different opinions, different answers, lets agree to disagree

still looking into supra engines in detail atm, but a senario is, imaging your doing 6000rpm and it snapps. you lose compresion so the engine is free to go wild and spin up if it feels like it, instead of go straight down immediately. at that point the oil pressure does not match what the engine is doing, thus , high oil pressure, causing other problems. i think its mainly more electrnic controlled cars, i.e bmw merc etc. i doubt it on a supra though

my bad

not on supras, just in general, if the belt snapps at say 6000rpm, and there is no control over the speed of the rotation then it can cause problems, ive seen it before, not much but seen it. i had it on a bmw 535td once, took ages to work it out but thats what it was in the end.

should have got a trolly and made out it was wildly out of control (yet more expensive than her car) and played "supermarket dent" with her car lol

really makes me angry when that happens, report it anyway, u never know

spot on cam belt can cause other damage though like, spinning your water pump so fast it mucks it up, or snap the tentioner arm, can even spin the cam too fast. if it goes a certain point can also cause oil pump problems!!

always report it to the police, tesco car park got me once but some nice lady spotted it and reported it aswell and thats how we got the :@'^%£"

look on the bright side, if your stuck somewhere and thirsty and your exhaust has condensation you have yourself a drink /vbb/images/smilies/bbcode_grin.gif /vbb/images/smilies/bbcode_grin.gif they should all be the same make really. check what make it is and post if poss deff o2 sensor though, wait for the new one or pop to your local motorfactors

moastly reps thinking there indestructable in there diesel wank-mobil. i got hit by a twat who was an illegal immigrant, no tax, mot or insurance and guess what? no licence, and who had to pay his court fees on legal aid~? all of us tax payers and i still had to pay £2k to fix my car......... :@
