HELP!! HELP!! HELP!! HELP!!
I have a 2006 Peugeot 206 with a KFW engine.
The thermostat broke – which has created a bit of a spiral...
I changed the thermostat, no problem there.
Then, when I filled up with coolant and was about to close the air screw on the engine block, the fragile brass screw broke, of course. Fine, I’ll try to see if a similar screw will fit. But no, the threads were stripped. But fine – there’s apparently plenty of material left. I’ll just drill the hole a size up and cut new threads.
As I start cutting the new threads, the thermostat housing cracks, and the area around the air screw hole crumbles.
Well.
I got a new thermostat housing and replaced it – scraped off the old liquid gasket and mounted the new one with a paper gasket.
After a drive on the highway, the car suddenly starts consuming a lot of oil. The car actually runs fine, with no major signs, except for the oil consumption. I notice that it uses oil more quickly when it gets hot.
I check the coolant, and sure enough, it’s clearly mixed with oil.
So, I conclude that the thermostat housing is not sealed. There’s no oil in the engine bay, so it must be the pressure between the oil and coolant in the thermostat housing causing the leak.
I’ve now replaced the paper gasket in the thermostat housing with liquid gasket from Loctite.
I’ve also changed the coolant, oil, and oil filter at the same time.
But....
When I take the car for a test drive afterward, I get the check engine light, and the engine becomes very sluggish in acceleration. Furthermore, the engine starts to “jump” a lot in the engine bay, and it’s puffing more from the exhaust.
I run a fault code scanner, and it spits out P1337.
The best I can find is that it refers to the impulse sensor on the crankshaft.
Since coolant has spilled out into the engine bay, I find it likely that this sensor could be dead. Especially since it sits just below the thermostat housing.
Now I’ve replaced the sensor. And even though I’ve cleared the fault code and changed the component, it still comes back after a while with the engine running. It’s still rough and jerky in the engine.
Does anyone have suggestions on what could be wrong?
