| Changed my woodruff key today and spent nearly an hour and a half getting the timing belt all lined up - eventually got it on then was time to test :-S ....now i rotated the crank through two full revolutions of the BELT and all was well, was quite stiff then would slacken off then stiffen up again ETC ETC (assuming the lobes on the cams yeah?) so then came the test..... primed the pump and sat there for 5 minutes absolutely shatting my kegs....double/triple checking that all the timing markers were lined up and they were - turned it over and an almighty BANG blew out the exhaust NOT the engine side.............. but this was enough to scare the shat out of me and ring Gipa with my tail between my legs lol so best case....i'm a legend, done it right and it was just excess fuel worst case.... i'm a twat and haven't timed it right. :>:S: Now the car DIDN'T turn over IE run, literally made this bang out the exhaust and i killed the key. How much would i be looking at best and worst scenario for a rebuild?? also name companies in the NE that could do this?? (assuming it would just be the heads would need building?) Got to wait until the GNR has finished tomorrow to have Gipa have a spy and start it for real | |

| Honestly depends on whats up with it mate. Could sit and list everything you'd need to build an engine from scratch as you dont know the problem but then it would depend on spec you wanted etc. Hopefully it'll just be something daft. |

| you will not have damaged the bottom end of the engine (the expensive bit) at worst you will have bent a couple of valves in the head if the cam timing was out. the best case is you have timed it wrong but you have had no piston & valve contact. a big pop out of the exhaust sounds to me like that is the case as the ignition will be going off at the incorrect time and igniting the fuel when the exhaust valve is open firing it down the exhaust. My advice would be, let someone that knows what they are doing do it in future it will be a lot cheaper in the long run matey! | |

| OK - i've taken the belt off again but pulleys haven't been moved... When i reference these pullies, its asif your stood infront of the car looking at the engine.... Hard to get a picture of the marks on this top-left...looks a TINY bit off Crank - hard to get a head on picture because i have a DSLR and with the lens it's deep and doesn't fit between the crank & rad top-right bottom right | |

| yad be looking at anywhere from £550 to £800 depending on how many valves you have bent, its quite time consuming replacing the valves due to solid lifters, V4 sti uses shim under bucket lifters and these have to be correctly measured to a hundredth of a mm, then machined exact in order to get the right valve clearance, theres alot more to it than simply fitting new valve

| The cam pulley will move when the belts taken off anyway due to compression. Hope its all okay bud. |

| So all the cams line up and match up their timing marks unaided or supported when the belt is off? im talking compression not combustion |

- Okay well it is the case on mine and various other cars ive changed timing belts on so apologies for assuming it would be the same
you keep forgetting peril, you own a NON TURBO.. you have 2 less cams... you have no boost ???? well you tryed boost?? with spectacular outcome but as normal you didnt listen too us lot??? cos we nar nowt dont we but must agree your googling powers have been helpful in the past | |

| Theory valves should be open equally on mine when timed as a turbo though surely? Just duration being different when running Jeez! I have one blonde moment as you all jump on the band wagon! Will always admit im still learning Oh and btw, Jonny you can fookin pedal to the meet tomorrow now! |
