Driving home from work today, I noticed the engine sounded like someone had thrown a handful of marbles into it, the car backfired a few times, so i pulled over and smoke started pouring out from under the engine bay - primarily from the drivers side turbo, i checked the oil, and the dipstick was smoking as well, but the level was fine, and the coolant temp & coolant level were ok as well - sound like a blown turbo? or something worse
yuk, sounds more like a big end bearing, or worse.. something has obviously let go in a big way.. dropped a valve maybe? hole in a piston? bearings dont generally make lots of smoke piss out from the engine though.. let us know how it goes! i'm curious now
Gee's Rathius, that sounds horrible!!! - however.... this presents the perfect opportunity to whack those new HKS turbos on! (amongst other upgrades)... ...i'm more of a 'glass half full' guy. :thumbsup:
Sounds like you droped the side out of a piston. Candu can confirm the syptoms. Do a compression check and then start saving some money:sick:
Re: Sounds like you droped the side out of a piston. Candu can Well looks like my radiator cap blew off halfway home and pumped the radiator dry- not a drop of coolant in her, and I checked before I left. I let her cool down, refilled her and at least it starts now, but there's a nice ticking noise coming from it now does that help narrow it down? I am resigned to spending a metric assload of cash on her now though, have to hurry up and order my injectors & pistons & 100k kit!!!
Re: Sounds like you droped the side out of a piston. Candu can mmm didnt u feel the cap blow off??? or even coolant following ur car behind u??? didnt notice anything? dammm so sorry to hear about this... good luck hope all goes in ur favour in the end :|
Re: Sounds like you droped the side out of a piston. Candu can nah it was still on...just one side of it was off its little lip - temp guage didnt move even a little bit off its usual spot, and no visible steam or smoke until the car stopped. :/
Ugh, it's a familiar story.. That's exactly what happened to mine, we were going for a drive to Tanunda, halfway there 'tickticktick', then exactly what happened to you. Except, by that stage, the head gasket and turbo seals were gone too (burnt the oil off the side of the block, a shitload of coolant hoses, cooked the turbos...a sad day.) And asshat from the RAA insisted that I drive it home, said it'd be fine.
Re: Ugh, it's a familiar story.. Same again to me on the Mt Mee zed run. My ticking noise mostly went away after the car cooled down. I already had forged pistons though and i think its just destroyed the oil rings.
Adam - I don't think there's any cheap way out of this. Sounds exactly like my problem. Do a compression check - this will I believe show you have one cylinder way down. (Mine were all between 165 and 170psi except #4 which was 40!!!) On stripping down the engine I found the landings blown out of piston #4. On the bright side it does give you the opportunity to fix a lot of other little things and engage in a bit of bling while you're at it like Baron is doing. If you can do this work yourself it will save you heaps. My total rebuild with all stock internals cost about $2600. Best of luck mate. Cliff
As a starter you have done a head gasket. when you pull the heads off you will find out if it has any other damage.
Re: As a starter you have done a head gasket. If you can do it go the way of Candu, my rebuild was $14,000. :thumbsdown: Alhough my forged pistons cost around $2000 themselves.
SNAP. I've had this as well. In my case the radiator lip the cap fixes to had become brittle ( it was plastic??? ) and the cap blew off on a long trip through the hills. By the time I noticed something was wrong it was too late. Had to have the heads heat-pressed because they'd warped. Still feeling the after-effects in my wallet...
Something that never seems to be mentioned is the heads going "soft" after an overheating event. All my machining has been done by Coorparoo Engineering & Performance (07 33976985) who rejected three sets of heads before finding a "hard' set o/haul. The soft ones can be used again but WILL fail (leaking head gasket) . The $14k mentioned is way over the top, unless it includes all labour from engine removal to installation. By 2morrow I will have a detailed pricing including 0.5mm overbore, forged pistons, crank grind and new bearings,heads match ported and polished with new valves,seats & guides, turbo's o/hauled by Motsons and shitloads of BLING ( one of the advantages of doing it at home)
Re:- Something that never seems Soft heads due to over heating . I have never come across this on any Zed site around the world, causing head gasket to go because of over heating. Electrolisis , corrosion , and pour castings but never soft heads?
2nd that, I understand how overheating causes them to warp, but surely when people HPC coat the runners / cryo treat the heads etc it would 'soften' the heads if what your machinist says is true. From what I was told, cryo treating also warps things. Also I would like to know how they tested it for 'hardness'. As far as I know, special machines are required to do this which aren't usually kept in workshops etc. Did they send them out to get them tested? I know to test some metals they use a punch like machine which measures the force going downward and then measures the dint left in the material or something along those lines. Did they do this?
