Howdy all,

Just as a bit of an update on my engine rebuild saga.



I've put the engine in the car, all the manifolds and associated crap are back on, and she aint firing.

Got some RIPPER flames comming out of the throttle body though, so I had a look at my CAS which I somehow managed to stab in COMPLETLY wrong, so I redid that. Fairly sure its right, tried again and it _nearly_ caught, but not quite.. so I took out the plugs, they were a bit wet with oil/fuel + some milky looking water.. Which I assume is why it wasn't running, since it had fuel/spark and compression.



Found out where the leak was comming from, I put a tiny whee little hole into one of the tension bolt holes near the exhaust port (not running with a sleeve here, tried to make the transition a bit TOO smooth).



So i'm going to have to fix that somehow, thinking some really high temp putty and then maybe put a bottle of "coolant stop leak" stuff through it, like I said its not a huge leak or anything like that, so I think that should work?



Any comments? what about just squeezing as much silicone as I can through this litle hole? I understand silicone will not stand up to the heat at all, but so long as it goes far enough into the hole it should stop the leak?



Please don't tell me to rip appart the engine and use a new housing, I realise this is the 'best' course of action usually, but I need this engine running and I don't have a whole lot more money left https://www.nopistons.com/forums/pub...IR#>/smile.png

TIG weld aluminum?

Do you have pics

well the only problem with welding might be that I may not be able to get the tension bolt out next time 'round?



And no, sorry don't have any pics of it.. don't have a digital camera (yet :-) )



Hmm im thinking i'm just going to have to give it a shot, with the exhaust manifold sealing putty and try to push as much of it as possible into the hole, then I think I will still run some chemi-weld sort of substance through it aswell.



Will keep ya'll posted on how it turns out in the next few days..

Aw jeez!



That milky stuff on your plugs could have come from that exhaust port, or it could have come from coolant leaking elsewhere...



Don't use chemi weld.



Don't use that exhaust putty.



The only thing I would recommend would be to weld it. Of course the only safe way would be to take it apart because if you weld it in situ there's a chance the heat will cook and melt the rubber seals.



Whatever way you go- good luck buddy!

ify ou are weldign the aluminum with the bolt in place the aluminum wont bond to steel tension bolt.
