escort mk1 Posted December 2, 2007 Share Posted December 2, 2007 have discovered a oil leak coming out of my top right engine mount hole. it was slowly coming out when the car is running so i took the bolt out and started it and it started pouring out. the only reason i can think this would be happening is if theres a crack in the hole. has this happend to anyone before? the only way i think i could fix it is weld the hole. then glue the head of the bolt onto the engine mount so it looks like its done up. only realised this leak once i had the engine running real good. cheers guys.

sholdowa Posted December 2, 2007 Share Posted December 2, 2007 ...that's the built-in anti corrosion system Unfortunately I think you're right. Time for a new block, really. Quote Link to comment Share on other sites More sharing options...
johnnyfive Posted December 2, 2007 Share Posted December 2, 2007 put some of that two part mix resin type stuff in the bolt hole, then torque 'er up... easy fix/probably not. Quote Link to comment Share on other sites More sharing options...
Unclejake Posted December 2, 2007 Share Posted December 2, 2007 Are you saying oil poured out of a top engine mount bolt hole when the engine was turned off? That would be very strange on a pushrod Ford motor. There is an oil feed to the camshaft around about that height but apart from that I can't think of any part of the Escort motors that would have any oil pressure in that area. If there is not high pressure oil then just clean out the hole with brake clean, clean the bolt with brake clean, smear the thread in either Locktite Thread Sealant paste or RTV Silicone and re-assemble. Of course you haven't actually said what type of motor it is so the above assumes a crossflow Ford pushrod engine. Quote Link to comment Share on other sites More sharing options...
RT Posted December 3, 2007 Share Posted December 3, 2007 fuck RTV.. it'll never seal.. you could clean it up and then fill the hole with 'Kneed-it' or 'Weld-it' stuff that you rub together like bluetack but hardenes as strong as metal. Then you can drill and tap it.. or just get a new block Quote Link to comment Share on other sites More sharing options...

Throwing out a block for such a reason is a bit extreme Quote Link to comment Share on other sites More sharing options...

Throwing out a block for such a reason is a bit extreme i agree 100% clean it up, loads of sealant on the thred in the hole and loads on the thred itself then wait till its just about to go off and tightin the sucker that will do it.

RT Posted December 3, 2007 Share Posted December 3, 2007 perhaps.. give it a go for sure.. just from experience I've tried to seal leaks lots of times with more RTV and it' always manages to seap past.. Quote Link to comment Share on other sites More sharing options...
d.p.n.s Posted December 3, 2007 Share Posted December 3, 2007 i put a big gash in a sump on my old mk2 gravil bashing it droped it in a ditch and hit a rock. had fuck all to fix it with so i cleaned sump up (on the car) got a plate about the right size loads of sealant about 30 rivits and it was gravil bashing time again i was only 16 at the time thatw as about 102 years ago. dan Quote Link to comment Share on other sites More sharing options...
Unclejake Posted December 3, 2007 Share Posted December 3, 2007 perhaps.. give it a go for sure.. just from experience I've tried to seal leaks lots of times with more RTV and it' always manages to seap past.. The trick is often to let it partially set and then tourque up the fastner some time later (hard to do if you are in a hurry). Hot oil will disolve uncured RTV but once it is properly skinned off it is usually an adequate barrier if the gap is not too big and there is not much pressure involved. It isn't the prefect brew and I used to be dead against it but I am becoming more inclinded to use RTV if the tolerances are not critical and the surfaces are not perfect. Having said that - in this applicationj (assuming the bolt hole has been drilled too deep and there is no crack) I would use the Locktite Thread Sealant Paste. That shit is awesome.

sholdowa Posted December 3, 2007 Share Posted December 3, 2007 My worry is that there shouldn't be a hole in the block there at all. I expect that there'll be a large split in the block in it's place soon. I certainly wouldn't put a bolt back in there that takes any sideways force...

eke_zetec_RWD Posted December 3, 2007 Share Posted December 3, 2007 3bond the, best shit eva. if its at pressure i wud be carful not to use need it etc incase you block the oil bath in the gallery... Quote Link to comment Share on other sites More sharing options...
escort mk1 Posted December 5, 2007 Author Share Posted December 5, 2007 The block is a 711m, 1300 crossflow motor. The oil only comes out when motor is running. If there is no bolt in the hole the oil really pumps out, so i thinks it must be coming from the oil gallery. With the bolt in the oil seeps out slowly. loctite paste sounds like it might be the way to fix it. How dose it react to pressure and temp. cheers Dave Quote Link to comment Share on other sites More sharing options...
escort mk1 Posted December 7, 2007 Author Share Posted December 7, 2007 hey guys borrowed some loctite paste from work that holds up to 200 bar and temperatures of 150 degrees. i'll degrease the bolt and the hole and then paste it and torque it up tomoro. doesnt say how long it takes to cure but it sets in the absense of air. hopefully its a easy fix. i'll let you know what happens on sunday!
