Managed to get the fuel setup finalised (hopefully). I had to move theblukhead nut to the top side. The bulkhead fitting is now sitting a bit proud, but everything appears to be fitting well.

Took the car out to try and sort the ABS (see my other thread) and bucking issue. I was hoping that the bucking issue was to do with acceleration enrichment, but it didn't really make any difference.

I also STILL have an issue with my cooling system. My rad cap setup is leaking so I need to check if I have my system setup properly.

Two steps forward one step back.



I decided to get my rad welded up so that I didn't have to worry about my dodgy pressure cap mod leaking.

I also had a few other things I wasn't happy with such as the heater hose routing through the front bumper and the leaking crank seal thanks to ATI sending me the wrong hub.

So it was rad out so I could kill a few birds with one hammer.

I decided to hack the Hinson rad up to keep it looking clean. I will get it welded up with the addition of some tabs so that I can mount a front and rear shroud. I made the rear shroud, but I am not convinced the fan I have is going to fit after I put this on. It will also give me the opportunity to paint the rad black. I got the paint to do it years agao :)

Building cars is no fun if you're not making improvements.  :)   I think that radiator fix is a good idea.

Got the crank shaft bolt out tonight. Always scary. It was covered in oil, so I guess it's good that I am doing this.

One thing that concerned me though is that the oil smelt of fuel quite a bit. I am hoping it is where the car may be running rich or because it's been standing a lot. Just hope it isn't blowby.

I have never changed oil in any LS that didn’t smell like fuel.

Crank pulley is off and I have cut some tabs to get welded to the rad so I can get that sorted soon hopefully.

I took off the front cover and knocked the seal out. One thing I did forget the first time round was that the are where the seal sits is damaged. In light of the fact I am having issues with leaks I think it's best to get a new cover. This is a pain in the butt as it takes ages to get stuff from the US... but what's new.

Rad is now at the welders.

I fitted the new front cover, but sanded the casting marks and painted it beforehand. It went quite well until I packed all my tools away and realised I'd forgotten the front cover gasket :banghead:

Still waiting for the ARP Crank bolt.

On the bright side, at least you haven't installed and torqued the damper.  :P

Well, I had. But there was enough wiggle room to slide it in behind.

Huh?  You said you were still waiting on the damper bolt from ARP..

Yeah, but I had put the pulley on and torqued it down with the old bolt.

My crank shaft bolt finally turned up, so I put the car back together.

I got the rad back in and, as expected, the fan now overlaps the shroud too much. The two options I have are ditch the shroud or find alternative fans. A dual, low profile fan setup would be nice, but I have no idea which to get (spal aren't readily available over here) and don't really fancy spending the money.
