Part 19 - Now or never
So im stuck on the fecking bolt in the block for the tdc pin. My usual hammer a socket method over the bolt has totally failed. Im stuck for a welder as my mates is borrowed out and thinking how the feck am i going to get this sorted asap. My man Alex was round that day finishing off the wiring in the garage - i show him the situation and he say he has a mig set in his garage. I convince him now is a good time to test out the new wiring with his welder
So first attempt was to weld a nut onto the bolt.

Bar on and snap ! penetration not great as hard to get in, oldskool stick welder and 2.5mm rods would be better. Try a few other nuts and no joy as its tight as feck !!
Last attempt was to blat a load of weld onto the bolt. this had the bolt glowing as cranked the settings up on the mig. Belted an irvin rounded bolt remover onto the blob of weld on the stud and the bolt cracks off with a bang, was tight as fuck !!

offending bolt

Time is cracking on at this point but keen to crack on, so next step was to pin the crank up. I pull the plugs out noting that they look about shot - makes the engine easier to crank over by hand. Wind the flywheel mark to the 0deg on the gearbox bellhousing and the tdc pin slides in lovely (pin wont go fully home when in the balancing holes on crank as messed about trying it for the crack)
Next step was to insert the horseshoe into the cams. I pop the seals out with a screwdriver and fit the horseshoe on the exhaust cam. Miles out as expected !


I leave it for now and start again the next day. First step was to buzz the crank pulley off. The bolt flies off with the beast

i note more tippex marks !!

Cam covers off more tippex !!

So next step is to fit the pulley lock

Dephaser allen key seal cracks off no bother and oil pisses out as expected. I manage to jack the engine up high enough to slip the buzz gun in to crack the dephaser bolt off which comes off easy. No room for buzz gun on exhaust so use the breaker bar and it comes undone with a crack.
Stripped
I then strip the cam cover off for resealing. Breather plate off first - then a load of m6 bolts of various lengths. Cams look to be in good condition

Cam cover gets a quick scrub with brake cleaner and stiff brush comes up ok. Inside is cleaned thoroughly

Anaerobic Gen Renault sealant applied - no pics as sticky and horrible. Cam cover back on and tightened in sequence / torqued to spec

New cam seals fitted - note gap for dephaser pulley on inlet cam seal

Exhaust pulley and new dephaser on, cam ends/pulleys & crank degreased thoroughly before fitting. New idler pulleys/tensioner and belt fitted. Rotate pulleys whilst still loose/pinned to equalise belt tension and set belt tensioner on the mark. Pulley lock back on & horse shoe back in the cams which have been reset to stock timing. Fit lower belt cover and fit crank pulley & new bolt and torque to spec.

Torque cam pulley lock to 80nm as per autodata as no figures for the tool in the workshop manual. I torque the pulleys up to spec noting a bit of dwell on the cam pulleys when torquing. Remove cam lock and the bloody horseshoe is off a little bit timing is out ! i note the cam slots are rough as somebody has been there before and semi fucked them using a non genuine timing tool at a guess

I then repeat the above a few times and timing is close but not bang on - no where near close enough for the horseshoe to slip in. This would probably be good enough for many technicians as the horseshoe will push in with a shove but as many of you know im pretty anal about stuff like this so its got to be bang on. At this point i have to ask for advice on whats going wrong and why timing is moving. The advice is to flog the cam locking tool up FT.
I nip the cogs up at 100nm. This makes the timing better as less movement but still slighty off. Next attempt i flog the cogs up to 140nm. This holds the pulleys rock solid - torque dephaser/exhaust cam to spec - remove all pins and rotate the engine a few times - Refit tdc pin and horseshoe slips straight in no worries. Good enough for me

so fit new seal into the dephaser next

Then get the other stuff back on as must hear it fired up now to check its all ok. Refit old plugs and wanky magnecor leads temporary to get it going. Crank over with coil disconnected to prime the new dephaser - engine is cranking fine with compression so just plug the coil back in and hit the switch. Fires up lovely and settles to a nice idle. Job jobbed

Long winded job but not too bad. Big thanks to
@SP33DY for borrowing me his pukka snap on torque wrench, sorting out crank pulley and generally awesome advice on it when i was stuck with getting the timing bang on.
Big thanks to
@R5turbo2 for borrowing the genuine renault timing tools
