RobMk4TwinCarb Posted June 19, 2009 Share Posted June 19, 2009 I was driving down the road today at normal speed in traffic when my engine started making a very loud rattleish noise which sort of sounded in time with the lifters. I pulled off the main road which was a good idea as the car lost alot of power and sounded worse so I pulled over took a look, decided was nothing to be done on the side of a road with no tools so tried to get it home. It got a few hundred metres and died so I turned it over and it gave me a backfire and a cloud of black smoke. So had to fork out a score to get recovered. Now when I try and turn it over it sounds a bit off not quite sure how but not right and won't fire. It looks like the water pump has blown it's gasket there is a sort of grey/whitish residue sprayed up from there so im guessing it's gone. I'm really hoping the noise was just the pump on it's last legs but I think im being too hopeful seen as it won't even fire now. I won't get the chance to rip it apart and have a good look for a while got a nightshift tonight and will sleep tomorrow just thought someone might know what damage i've probably done and save me a bit of time when I do look at it. It's a 90' EFi. Having a great time ! Rob Quote Link to comment Share on other sites More sharing options...

Guest Alanman Posted June 19, 2009 Share Posted June 19, 2009 If its spraying water the bearings in the water pump may have colapsed and if it has there's a good chance its loosened the belt and maybe jumped a tooth. Check the timing is not out Quote Link to comment Share on other sites More sharing options...

Admin Paul Posted June 19, 2009 Admin Share Posted June 19, 2009 Yes more than likely jumped a tooth or 2, stupid cam belt design Paul Quote Link to comment Share on other sites More sharing options...
RobMk4TwinCarb Posted June 21, 2009 Author Share Posted June 21, 2009 It had jumped about 5 teeth! I ripped it apart today took the pump off and I can say the only difference between that and the new one was that the old one went round alot easier didn't sound off or anything. While it was all off I took the oppurtunity to pressure wash all the oil and rubbish that had built up over the years at least made it a bit cleaner. Put the new pump and belt on, timed it up as best I could then had a crack at starting it. It started but was rough as and would only stay started with a good few revs had no tick over at all and stunk of fuel. I then got the rocker cover off made sure the cam and valve springs were at least in one piece and they look fine, whacked in some new lifters while it was all off. I gave the timing a tweak started it again with a very slight improvement the tick over was still like being inside a giant vibrator but it would still run with some encouragement. I put the airbox and the bit that goes from that to the throttle body back on then it wouldn't fire at all which gave the battery a chance to decide it had enough and give up. At which point I gave up for the day im hoping it was running so bad because I had got water in somewhere it wasn't supposed to be but probably not. It seemed really like the timing was well out or only running on 2 or something i'll have another poke tomorrow I guess anyone with any idea's is more than welcome to suggest them!

Guest TSR157 Posted June 21, 2009 Share Posted June 21, 2009 proberly bent valves in it now Quote Link to comment Share on other sites More sharing options...
RobMk4TwinCarb Posted June 25, 2009 Author Share Posted June 25, 2009 I don't know if this makes any difference or not but I think my ISCV might of been knackered beforehand it had a bit of a rough idle and would run lumpy every so many seconds, unplugging the ISCV made no difference to the way it idle'd. Never had an efi escort before so all bits like this are new to me. Im really hoping the valve's are not bent but if they are can you use any 1.6cvh valves? As I have a whole cvh carb engine in my garden, and an mfi head somewhere else. I have read somewhere that the cvh is supposed to be a "non-interferance" engine and as such the valves and pistons shouldn't collide even with the timing out ? I am gonna try and mess with the timing some more today as the backfiring and blowing air back out of the airbox seems timing related ? Im not a mechanic everything I have learnt has been through doing things myself, so if im missing anything obvious that would be why Quote Link to comment Share on other sites More sharing options...
RobMk4TwinCarb Posted June 27, 2009 Author Share Posted June 27, 2009 Valves are well wonky now ! Piston's took a beating too but are in one piece. Some pics anyway.. Quote Link to comment Share on other sites More sharing options...
RobMk4TwinCarb Posted June 29, 2009 Author Share Posted June 29, 2009 Spent the last couple of days swapping valve's over and cleaning my head up. Got my head gasket and bolts today put it all back together and it works ! Well it works as well as it did before it broke so it'll do. Some pic's of the before and after of my head...if i'd had more time i'd of made a better job of it and polished the intake and exhaust but they just got de-coked. Woo it works !! lol Rob Quote Link to comment Share on other sites More sharing options...

Guest murcus Posted July 9, 2009 Share Posted July 9, 2009 (edited) congrats, nice job ! whilst you were replacing the few bent valves, i would have just replaced the 8, as that was, you know, none of them are going to have sticking problems, and the new valves would seat alot better than the old carbonated ones did you change all the valve stem seals whilst the head was off? did you use sandpaper to clean the head? ( what i normally do, is take out all the valves, strip the head completely, of all the seals etc, take an old basin and couple of bottles of cillet bang, and drench the head in this for a day or two, its amazing the effect it has on the head, as cleans out all the ports and deposits, after you power wash the head, then would send for a skim) Edited July 9, 2009 by murcus Quote Link to comment Share on other sites More sharing options...
RobMk4TwinCarb Posted July 9, 2009 Author Share Posted July 9, 2009 I did do all 8, didn't change the seals or the guide's it was a get it all going as quick as possible thing and as cheap which is why I used valve's out of another head(after a bit of a clean up), not new one's. I used a flapwheel with polishing compound after a decoke with a thin wire brush and alot of buffing ! The surface of the head just got a good buff up and a good clean with white spirits as it was all I had laying about, did a fairly good job though. Cheers for the cillet bang trick i'll remember that one Rob Quote Link to comment Share on other sites More sharing options...

RobMk4TwinCarb Posted July 11, 2009 Author Share Posted July 11, 2009 It should be ok now cheers lads still got to play with the timing and hopefully try and fix the ISCV and hope that the noise I can hear is the manifold blowing not pinking ! But yea it's getting there lol Quote Link to comment Share on other sites More sharing options...
