Engine not turning over after rebuild.

[ya53lhd_MATT]

Have just finished rebuilding my F4R engine, have had it turning over by hand in the work shop (10x) , dropped it into the bay, tried turning it over one more time before starting it up and it's turned a little over half way then come to a stop.

Parts replaced, Big end bearings, APR's, Rings, Valves, Oil Pump, Water Pump, Cambelt Kit, All Gaskets + Seals

Has been timed up with the correct timing tools.

Sort of an over night thread before it can be looked at again tomorrow, any ideas guys?

[Sam@NP]

Can you turn it over by hand?

Can you turn it over by hand?

Come on, the answer was in the first line

 

[Sam@NP]

It wasn't though was it.

Can you turn it over by hand now its stopped mid turn by the starter?

 

[ya53lhd_MATT]

Hasn't been tried off of the key at all and no it wont turn over by hand, almost like it's been damaged putting it in to the car, but certain it wasn't :/ thanks for your interest Sam

 

[Sam@NP]

Stupid question, is the crank pin out?

It's not helping as I've know idea how to help you, but dropping it won't help

 

[ya53lhd_MATT]

Sam, yep the crank pin is out was the first thing i checked ;p

 

[Sam@NP]

Check to see if its gone into gear if the box is attached and whip the cambelt cover off and have a gander. Cant think of much more apart from something not done up properly inside.

 

[Fred@BTM]

take the plugs out and try again, if it still locks up then it needs pulling apart

 

[mr.pink87]

Stupid question: Is the gearbox in neutral?

 

[ya53lhd_MATT]

Will check that it's not in gear, didn't even cross my mind, it was getting late and panicking if I am honest, if that isn't the case I will try it without the plugs in, thanks guys! Appreciate the input, fingers crossed for tomorrow, update to follow...

 

[st3ve]

Sorted it?

 

[ya53lhd_MATT]

It wasn't in gear :/ and it wont turn over without the plugs in! Rocker off, nothing suspect starring at me! Sump off tomorrow to inspect the bottom end. Any other idea's. Will turn 3/4, and then back 3/4's

Cheers guys, anyone nr bristol wanna come and get involved???

 

[Neal 182]

Sounds like timing to me was the bottem pully torqued up right recheck the timing again first

 

[ya53lhd_MATT]

Have checked the timing again mate, it's spot on still, so nothings slipped :/

 

[Dan@SJM]

One of the cams 180* out?

 

[ya53lhd_MATT]

^ surely it's not possible for the cams to be fitted in correctly if it's been timed up with the correct tools?

 

[mark123]

It would still turn over by hand if one or more cams were 180 out.

You did lock the bottom end as well as fit the cam locking tool when you checked the timing?

 

[Michael Woodford MST]

Did you fit new oil squirt jets??

The piston maybe hitting them.

 

[ya53lhd_MATT]

Yep, bottom end locking pin was in mate :/ no new oil jets fitted, sump off, nothing suspect either, could it have anything to do with the fly wheel? Really strange

 

[ya53lhd_MATT]

Sorted had a bolt sitting on top of the piston :/ must have fallen through! Cheers for all ideas guys

 

[The Chubby Pirate]

Well done!

 

[ya53lhd_MATT]

Danny, not very clever I know! Least it wasn't anything more serious. Luckily I had another set of new head bolts, Should have it running by tomorrow

 

[The Chubby Pirate]

Fair play to you for even taking that on!

I wouldnt know where to begin! Im keen with spanners but keen and know-how are completley different things lol...

:headno: oh dear!

 

[ya53lhd_MATT]

I was worried to begin with, allot of stigma on here that its too complicated for anyone but a Renault specialist to work on, but in my honest opinion I don't think that's the case as long as you have the right tools and I suppose a fair bit of mechanical knowledge,

Will say a big thanks to Fred over at BTM, who took a call or two off of my old man for torque settings, really help full and to have that sort of help out there!

 

[The Chubby Pirate]

My old man is a mechanical engineer recently retired, great at what he does - his words were "f**k THAT" when asked about changing belts etc lol

Just aswel you checked by hand again after dropping it in the bay as im sure a few people would of thought... Aww well it turned over by hand while it was out and try straight off the key

 

[ya53lhd_MATT]

I reckon it would of made quite a racket if I did just fire it over

Lol at your dads response! Have you done your belts?

 

[The Chubby Pirate]

I havent yet mate no (Phase 1 172, 122k belts done at 77k) Im in a predicament as to what to do with it...

Its worth virtually nout in the grand scheme of things however its been good to me so far since April. I'm needing a 5 door soon though so would hope its going to last until i see what the new Clio 4RS is like. I will end up getting the belts done, i simply cannot let it die. I'm too much of a fan boy to let it. Also its number 2 of 172 of the exclusives, almost sacrilege to send it to snapped cambelt heaven lol..

 

[jon_r]

Get everything you need, the guide with all the settings in it and a spare day. Lay everything out, make a brew and crack on. It's not rocket science. Just check and double check everything as you go.

The head bolts are reusable. Just need measuring.

 

[Cupman29]

The head bolts are reusable. Just need measuring.

What do you torque them to if you are reusing them or do you still angular torque them?

 

[ya53lhd_MATT]

She's running, sounding sweet as a nut too pardon the pun!

Not sure about torque'ing used bolts up mate, literally had a set I ordered before ordering a full head gasket set which came with another set (dunno if that makes sense) meh, so used them anyway. If anyone's after a set, let me know!
