I pulled the 1.8 L motor in order to fix all the rust in hell hole which of course gave me the opportunity to fix a few things.
Pulled the heads as the lifter tubes were all leaking oil profusely. Heads/Valves: Looked to be in good shape with minimal carbon buildup. I was surprised. Pistons: Look OK I guess... not sure what they’re supposed to look like? They had light carbon buildup on the top of the Pistons but otherwise seems to be OK. Questions: Do I buy a new stock pistons and cylinders? if not should I at least change the rings or does it matter? Can I upgrade to a slightly larger piston without changing the heads and using the original FI? Should I get one of those modified type 1 oil pumps to replace the oem? I just want this to be a reliable weekend driver that I can drive through wine country and go coffee and cars. |

When you buy pistons, make sure you get the correct pin height. The 2L has a different measure due to the longer stroke.
There are 94 and 96 pistons for the 1.7/1.8 crank, if that's what you want to do. Regarding the oil pump, the type 1 has no advantage over the type 4. On the contrary, it's a bit of a headache to get the right one and to make it fit. It also has more places to leak from. The only reason for a type 1 is if your type 4 is bad and can't find a new one (NLA) |
