Noticed the vacuum was lower in 1574 than normal and it threw a P0171 code. Also noticed the EBC wasn't lowering boost when I turned it down. Checked the WG and the diaphragm was leaking. Unhooked it for now, good thing it has a forged motor or it would have blown the stock rods to smithereens.
It also is still bubbling coolant out the overflow, mainly at idle. Doesn't appear to be overheating. I removed the thermostat, swapped to a massive CS radiator with a different fan and cap, flushed the coolant with fresh distilled water and burped the system. Has to be the water pump.
I rebuilt the head on the stock motor right before the rods started knocking so I think I will go ahead and swap the head over, install the ZE intake and CS exhaust cams, possibly get some hydra cam gears and cut and paint the valve cover. Then install my ZE intake manifold, new water pump and blue gates timing belt/components, Steedspeed mani, low mileage T25 and Forge WGA with new 14psi spring.
And I ordered a vacuum pump that just came in so I can recharge the AC in both cars and fix the leaks.
As for 1574 I ordered new main and rod bearings, will have the crank polished and put it all back together. Probably should have waited to order the bearings until I had the crank out but I have a spare good crank so I should be alright.
