Kaan W Posted November 20, 2012 Share Posted November 20, 2012 (edited) I took a little trip to the bodyshop this morning and they said my car has a small oil leak with a puddle on the floor approx 4" in diameter after the car sitting there for a couple of days. After getting under the car its actually water but couldnt smell antifreeze in it. The puddle is directly below the gearbox sump. Any ideas where this would be coming from? Does any of the rain water get directed under the car around that place? Could the block be cracked somehow? Thanks Edited November 20, 2012 by Kaan W (see edit history) Quote Link to comment Share on other sites More sharing options...
Robert Posted November 20, 2012 Share Posted November 20, 2012 Could be a bugger of a heater pipe that goes right at the back of the engine bay (towards wind screen). Goes from left to right and is quite central just behind the cam covers. Had that leak on me once and took me an age to find. Quote Link to comment Share on other sites More sharing options...

I just hope its not a cracked block or something. Would the engine still run if its a cracked block? Cause it runs fine. Quote Link to comment Share on other sites More sharing options...
Hellstrom Posted November 20, 2012 Share Posted November 20, 2012 Check all heater hoses there are a few under the intake. Water takes all strange ways. Car would run if the block is cracked yes. Aslong as its not cracked into multiple cylinder but i Really doubt that is the Case. Check core plugs while you are at it. Quote Link to comment Share on other sites More sharing options...
Kaan W Posted November 20, 2012 Author Share Posted November 20, 2012 Yeah i'll check all round that area. The only reason I was thinking it could be a cracked block is because when I filled the car with coolant I poored it in the top rad hose while the engine was still hot. but then again when the thermostat opens that lets the cold straight into a hot engine. Its probably something simple... Quote Link to comment Share on other sites More sharing options...
Robert Posted November 20, 2012 Share Posted November 20, 2012 I highly doubt it's a cracked block. It will more than likely be just an old warn out rubber pipe that is probably a pain to get to but cheap from Toyota (well it was a few years back). Don't stress it's just one of those things that's needs replacing rather than a major problem. Quote Link to comment Share on other sites More sharing options...

Kaan W Posted November 20, 2012 Author Share Posted November 20, 2012 No it doesn't, the stat doesn't open till the water gets to whatever the stats operating temp is, in the case of a mkiv a stock stat is i think 82 C Pooring cold coolant into a hot rad or engine is a pretty daft thing to do as all you do is end up with most of it coming back out at you. I would say I poored about half a cup full in then realised I could crack the block so I poored boiling water from the kettle into it and it fixed my problem of not being able to bleed the coolant system by opening the stat and letting the water rush into the engine.

Dnk Posted November 20, 2012 Share Posted November 20, 2012 (edited) I shan't divert your thread but you really don't have to take any hoses off or pour boiling water into it to make the stat work, you just need to run the engine up to temp and if the stats working correctly it will open and you also shouldn't get coolant or water leaping 2ft out the rad while its warming up. Back to your leak, if it is coolant then the prime suspects are the heater matrix inlet and outlet pipes.

Back to your leak, if it is coolant then the prime suspects are the heater matrix inlet and outlet pipes. Thats what I thought should happen but it didnt for the only reason I can think of is after the water shot out the engine there was no fluid touching the stat which meant it couldnt open even after the engine was warm. but as soon as I poored some hot water in the top hose it come into contact with the stat and opened it then the fluid level in the rad dropped and I topped it up from there. I'll have a check around the heater matrix hoses for leaks. Cheers. Quote Link to comment Share on other sites More sharing options...
Dnk Posted November 20, 2012 Share Posted November 20, 2012 No coolant in the engine is the reason the stat didn't open then, next time just fill it up using the rad filler and guarantee it will work if the stat is working. Good luck finding the leak and don't forget to get some antifreeze in the coolant Quote Link to comment Share on other sites More sharing options...

Thank you and I will Quote Link to comment Share on other sites More sharing options...
Geo Posted November 20, 2012 Share Posted November 20, 2012 check the two main hoses at the top at the back of the engine, that sit on top/front of the spark plug cover, i had this when i changed my plugs. i took the hoses off for better access, put it all back together, but FOTGOT to put one clip back on. I reckon when the car is warm and upto temp, the coolant just started to pour out slightly. I only ever noticed it when the car was sat for a while Quote Link to comment Share on other sites More sharing options...

GazB Posted November 20, 2012 Share Posted November 20, 2012 mine was sat for 12 months in a nice garage, when i decided to take it for mot i left it tickinbg over for a while and it developed a water leak, down the rear of the engine area, after it was inspected we noticed a small pin hole in the rear core glug. Pain in the arse to remove and replace, but cheap a part. Job done, new water/anti freeze and no worries for a while on that front Quote Link to comment Share on other sites More sharing options...

I'll have to check when I get my car back but im hoping it was from another car in there before mine or something spilt lol. I couldnt see water dripping from my car so with a bit of luck its not the car. Quote Link to comment Share on other sites More sharing options...
