Renault mystery running problem

[2F45T4U]

Mate has had work done to his renault Clio in college as the water pump had seized<br>
<br>
Heres whats been done to it<br>
<br>
"we stripped it down skimmed head and put new water pump and head gasket on. then put it all bak together<br>
<br>
started it up and it ran fine<br>
<br>
ran for about an hour waiting for fan to cut in before realising fan wasnt connected. <br>
<br>
connected fan (electric) and as we did engine died.<br>
<br>
went to start it back up and something is very wrong<br>
<br>
do a compression test shows that there is no comprssion in any cylinder<br>
<br>
Not even 1 PSI!!!<br>
<br>
check clearencs on tappes and there is no gap at all. slackend them all of and still nuthin<br>
<br>
timing is set up perfectly"<br>
<br>
<br>
<br>
Evne the college lecturers are stumped!<br>
<br>
<br>

how much got skimmed off the head?

<p></p><i></i>

[george]

sounds like it got a bit too warm and has seized the cam <br>
and taken teeth off the belt<br>
the cam is of course on the top and would get pretty warm if the fan wasn't cooling things

[george]

had a volvo 245 once with no oil pressure too the top it had seized the cam removed the camcleaned it up put cam lube on it to run it whitout the cover on to check if it was getting any oil before i got out of the car too check it stoped <br>
so just pulled the head and sump cleaned the oilways and brought it back to life after that it did a few trips to the south of france

Sorry to sound mean here, but your lecturers let an engine run for an hour without any cooling?<br>
<br>
Was this some sort of destruction test or were you too busy looking out of the windows at the hockey team? <!--EZCODE EMOTICON START :rollin --><img src=http://www.ezboard.com/intl/aenglish/im ... s/roll.gif ALT=":rollin"><!--EZCODE EMOTICON END-->

And these are the people who train "mechanics" to then be let loose on the public...<br>
<br>
What was he thinking of? Or maybe like me he was a pathalogcal hater of cheap french tat...ha another one for the scrappy...bring it on.<br>
<br>
35 quid a ton I hear...<br>
<br>
Being serious....sounds like you need another higher quality head gasket and possibly a temp guage? I know some cheap frog crap only has a warning light...fat lot of use that is!<br>

got a 1.9 d and a 1200 energy at hand (not my sons)<br>
if richards mate needs one

Some of those early Clio Head's should only be skimmed to clean the face only.<br>
<br>
1200 and the 1400's where also prone to oil leak's from the head gasket.<br>
<br>
And to top it all the latest Renault's use Nissan engine's<br>
(Clio 172/182 V6Sport to name a few).

Sheered wood ruff key <!--EZCODE EMOTICON START :lol --><img src=http://www.ezboard.com/intl/aenglish/im ... /laugh.gif ALT=":lol"><!--EZCODE EMOTICON END--> <br>
<br>
2 bent valves....

[SprintV8]

was tighten to what torque setting?.<br>
<br>
Did you use new head bolt's as they are the STRECTHED type.<br>
<br>
Head bolt like this?.<br>
1) 20Nm<br>
2) 90 +- 6 degree<br>
3) Wait 3 Minutes<br>
4) Slacken Bolt's 1+2 then tighten to 20 Nm + 200 Degrees<br>
5) Repeat Step 4 for bolt's 3.4.5+6<br>
6) Repeat Step 4 for bolt's 7.8.9+10<br>
<br>
They should be 3 number's after D7F

we stripped it all down again today and found the problem. sheered woodruff key. apparently it is a common fault. in renault garages they supposedly change the crankshaft pulley when a timing belt change is done. another fitter from renault had one sheer on a test drive. the car doesnt have a temp gauge only a warning light<!--EZCODE EMOTICON START :eek --><img src=http://www.ezboard.com/intl/aenglish/im ... ns/eek.gif ALT=":eek"><!--EZCODE EMOTICON END--> load of use that is. anyways. pulled all the valves out again to check for bentness as when the key sheered the cam rotated 180 degrees. the result is now two bent valves and a gutted owner. <br>
thanks for he offer of teh new engine but the engine in his clio is a 1.2 diet not energy. maywell come in handy when hes killed his though<!--EZCODE EMOTICON START :rollin --><img src=http://www.ezboard.com/intl/aenglish/im ... s/roll.gif ALT=":rollin"><!--EZCODE EMOTICON END--> <br>
thanks for the suggestions<br>

The woodruff key only normanlys breaks when the crankshaft bolt hasn't been tighten correctly.<br>
<br>
20nm + 90 degree's from memory depending on engine code.<br>

engine number on car is d7f. the head torque settings were unreal<br>
12 stages. tighten 1 and 2 to 20nm then 90degrees the slaken off then summit else bla bla. we done it all right nd now we got to get another one<!--EZCODE EMOTICON START >: --><img src=http://www.ezboard.com/intl/aenglish/im ... ns/mad.gif ALT=">:"><!--EZCODE EMOTICON END--> <br>
ahwell. its all good practice<!--EZCODE EMOTICON START :p --><img src=http://www.ezboard.com/intl/aenglish/im ... tongue.gif ALT=":p"><!--EZCODE EMOTICON END-->
