Mk1 F4R/172'd Track Car Project [Year 3 - Engine and Chassis Rebuild]
Re: Mk1 Hybrid Project
Few productive things done today, along with a few unproductive ones...anyway...
After fitting the downpipe and setting the length when the engine was in, I had the 'adjustable' bit welded up...Then I painted it with high temp paint, along with the manifold itself too...
Also dropped the gearbox off to get the circlip welded into place...hence why the fork and release bearing are in that pic...
I had some exhaust wrap left over from when I did the williams manifold and downpipe for the F7R, so decided to wrap the downpipe with that, and Im going to get some more to do the manifold itself too. Once i had wrapped it, i realised there wasnt enough to do the complete downpipe, lol...so going to have to add a short bit when I get some more to do the manifold...
Next, went back to the factory to get the head off the engine...yet more fun. Didnt have the cam locking tool to get the pullies off, so improvised with the old cambelt, a bit of force and a few people. Cracked the exhaust pulley off after a few attempts, and then removed the cam cover with the inlet cam/pulley still 'attached' to it, such a GAY design. Gona have to get that pulley buzzed off tommorow.
Anyway, looking around, noticed a problem...one of the studs had bent...think it was when we had the cambelt in place round the exhaust cam using it to get the pulley off
Anyway, Matteh to the rescue with the part number for a new one, off to renault tommorow...meh.
Still need to get the crank bolt sorted, attempting to knock it round didnt work, seems like its stuck in pretty tight....

Re: Mk1 Hybrid Project
lol, issues indeed.
I painted it so its a clean surface for the wrap to go over, I was told by a few people its recommended to do so, so if water gets into the wrap when its on the car, and its sat in the wrap, it dosent start rusting the exhaust inside....
Wrap is pretty easy....wet it, start at one end, make sure you keep it tight, then use stainless ties. When it dries it gets tighter...Then i spray it with some silicone heat wrap sealant to keep all the crap out (double precaution)

Might aswell get some forged rods and high comp pistons in there while your at it, Jord?

Re: Mk1 Hybrid Project
ello mate just a thought, the crank bolt why not weld another bolt to it and try taking it out like that?

Re: Mk1 Hybrid Project
Bit of an update, few things started to go right again...
Drilled pilot hole on the snapped crank bolt, then bigger hole, then used winstons thread extractors which failed....Got some heavy duty extractors and it came out pretty easily
Next up, the bent stud...
Sorted....then cleaned up the head and the block....
Also picked up new cambelt, new headgasket, etc....

Make sure you check the head and block for flatness!

Re: Mk1 Hybrid Project
have done with a steel rule. cant see any light though/gaps at all in any direction, even down the gaps between the bores....
None of the white spirit had gone from the bowls when I got back...valves must be reet...
Dont know if to get it skimmed or not if its flat...mehhhh

Get a bit taken off, higher comp ratio is a bonus aswell.

Re: Mk1 Hybrid Project
yeah but still....how was it stuck and not turning over lol, thats the thing
how much is a light skim? thou wise, i can get it done tommorow easily, just weather to bother or not...
Got new crank bolt + new stud for tensioner already, along with the new belt. Got someone coming with the timing tools tommorow to time it back up....

What yo' talkin bout! :evil:
Least you won't have to grind the valves this time
What yo' talkin bout! :evil:
Re: Mk1 Hybrid Project
ah cool...any particular reason why though?
3 thou, at a guess
surely the skimmer will know how much it needs off. we just give our guy them and they come back skimmed lol
daddy just told me dont bother with skim
ah cool...any particular reason why though?
Re: Mk1 Hybrid Project
cos you took it off correctly and have checked it, saves few bucks too

Re: Mk1 Hybrid Project
yeah 172 starter mate.
Just got back in now, engine back together with new HG...new cambelt, timed up...still wont turn over by hand, well....from the crank pulley it wont, the bolt just gets tighter instead of turning the engine over....But if someone turns the flywheel with screwdriver, and someone on the crank pulley, it turns over (pretty stiff)....
