Since my RV 12 is factory built Vans tells me I can't modify the engine with a Thermostasis, I have applied foil tape to the oil cooler and that's helping with oil temp but my Cylinder Head Temps are consistently low and there's no cabin heat available. Can I put foil tape over the air inlets at the front of the cowl to try to warm things up, or carve a plug out of Ethafoam that would partically block those two round openings?
