Recently completed rebuild of 1.8L and it's running too hot. Oil temps climb to 230 with only about 10 minutes running. It doesn't matter how the engine is loaded. Items to consider: 1) case cleaned and checked for alignment; 2) LN pistons installed at 96mm with new Nickie cylinders; 3) cylinder heads (1.8L) cleaned and set for 8.25:1; 4) new connecting rods; 5) push rods check out OK; 6) car did not previously have thermostat or cooling flaps, so these were installed. Thermostat opens as it should at 180; 7) Air/fuel ratio is 12-14 and within spec; 8) engine timing within spec; 8) mild cam upgrade. 9) crankshaft and flywheel were balanced; 10) all engine tin is in place
Could it be that the engine cooling flaps are not working or reversed? All thoughts and commentary are welcome. This one has us baffled. |

I have NEVER had any thermal control issues with a Nickies engine! That includes 280HP N/A T4 based engines running in Florida sumer heat.
You have something misconfigured, mis-tuned or some weird variable thats creating this issue. |
