VR4 Block Weld
Not as scary as it sounds, I noticed a tiny little crack where the lower front engine mount bolts up to the block.
I used a flywheel bolt in there so we are guessing that the bolt may have hydro'd it during install on the new block.
The previous block didn't have an issue but it is quite possible that different tooling is used when making different blocks etc etc (2.0L vs 2.4L)
Anyway, Barry from BJP was arranged to weld the block @ Springy Motors using the Tig @ Springy.
Now everybody says that cast iron welding is difficult, but not with Barry. The welder @ Springy was a LICOLN welder which is about $12k worth. Barry was highly impressed with the welder and in all honesty, the job was done within the hour.
I supplied a dummy block (my old block with the cracked sleeve) for test welding. A few adjustments later we were ready to do the block in the car.
If anybody needs cast iron welding (manifolds / exhaust housings etc, organise it either with Springy Motors or BJP.
Hair-line crack
Crack die ground out
BJP in action
All fixed
