Focus Part 2

[wander2039]

So this is part 2 with this hunk of junk. There was pieces of valve seat still left in the intake despite my cleaning efforts. After I emailed the company they sent me a link how to clean the intake properly.. would of been nice if that was on their website. Not happy but not blaming them. Regardless everything on this take two rounds so would of been something else.

Not buying anything else for this. Going to try smoothing out the damage and slapping it back together. Need to get another grinding stone and see if it can be smoothed out more. Going to clean the head gasket and bolts, might turn it a extra degree. Did find more valve seat still in there. Was driven less than 10 miles.

Interesting to see if it blows up. Probably should replace the piston but don't want to take the bottom half apart again.

If you have a local machine shop you could try taking the head down a bit. Would increase the CR a touch but if there is plenty of clearance that's not going to be an issue.

I have a friend who had an old Focus with the SOHC engine. He sold it cheap to a neighbor and warned them to replace the head asap as a preventive measure.
There is a $250 Chinese aftermarket head for the Focus that is more reliable than the Ford original.
His Focus ate cheap Rockauto motor mounts and the car was a POS for the mileage on it.

The Duratec is, this is the SOHC engine.

Cool, learned something new

The early Focus had the 2.0 8V SPI engine from the late 90's Escort.
Terribly archaic in design when compared to the Japanese, with the refinement of a 1910 John Deere tractor.
Aside from the valve issue, they were very reliable. Far more reliable than the 16 valve engines offered in the later Focus

Many can be seen running today with 200k+ miles with little to no oil in the engine.

This head was rebuilt in US not China. The motor mounts are a issue the trick is using the strong dogbone mount.

Ouch I wouldn't say a John Deere, yuck. It did sound like our old Allis's with no valve seat. Orange is always better lol.

Round two..

Reused the head gasket and bolts but put some copper gasket on it. Changing the oil tomorrow and test drive.
