Hi guys I have just discovered a crack in my TT LS1 block. It is in a bit of an unusual place as it is in behind the starter on the lower side of the block (see pics). The only thing it is doing is leaking water (no water in the oil and engine runs fine!). I am just wondering if anyone else has had 1 crack here, what may be the cause and should I just weld it up? The engine has about 4000 miles on it, has a head stud kit and runs up to 20lbs (a lot I know! though not often)
Any input would be appreciated.
Seems like the best thing to do is weld it to stop the leak. But you got to wonder, what cracks you can't see on the inside. Swapping for a new block might sound extreme but on a boosted engine you don't want to take any chances.
looks like your losing some coolant fromt he coolant plug right there as well. I wonder if it isnt more damaged then it appears. IMO if you spend the time now to swap out the block, at least you can salvage all the internal parts....if the block cracks during a run you might not be able to save a damn thing inside that engine.
