Here she is, arriving after a 3 hour tow. My truck had a flat on the front left after hitting road debris. The U-Haul trailer was great. The surge brake is required with the F150 ruling out the local contractor's rental yard.









































This has been in a barn for a while and was super dirty. There was almost 2" of dirt behind the access panels but the rockers look surprisingly good for their 39 years.

Looks like an easy project. Let us know how it goes.

The head is toast. A cracked valve, valve recession, and deep pitting will send this one to the smelter.





I have a '74 head on the shelf that seems to be in good condition. It will be stripped, checked, and if need be, sent out for service. 

The valve springs look like DMS competition items.



I may have to throw a 107/ 104 setup in there!

Work on the replacement head is progressing.  The valve seats were replaced by the PO. Just a bit of lapping is producing a good seal that is tested with paint thinner. Unfortunately, two of the valve guides are out of spec.

Has anyone seen these pistons? This is a 2.0 bored .030 over with what appear to be forged pistons. I'm wishing and hoping that the PO used a HC piston.

SJ Sportscars sell 11:1 pistons for the 2.0, you could email them to see if they can compare pictures. You may be in luck.

Close! The SJ pistons seem to have a cutout along the side of the valve pockets.
Mine look similar to the stock piston but the valve pockets are .010" shallower. The center area is dished .150" compared to the stock .155" so it's .005" shallower. At tdc the edge is .012" below the liner.
I don't think this is a HC piston. These small differences couldn't add up to much.

Later spec European engine then, like mine. 9.5:1 roughly, a lot better than the Federal 8.4:1.

I jest called Mike at Delta Motorsports. He said if they're dished then they're stock compression. Oh Well.

I, unfortunately, had to do a shimming job and it did it on the car...what a horrible experience...it took me two days to get it all right....and I became quite adpet at using a small micrometer and a set of thickness gauges....sigh....

I finally removed the door handles and locks last night. I had been dreading this project since there is little room to work in this area with my size XL hands.

After searching the forum for clues I found the information in the first post to the Body and Interior forum in 2005.

Step 1: remove "vent" glass and frame. remove the two bolts in the recesses near the top of the door. Then remove the nut that holds the window channel at the bottom of the door. The entire frame and glass can then be pulled up and out.

Next, with the glass in a 2/3rds up position, slide the glass towards the front of the car until it is free from the regulator and remove.

Now the back of the door handle and lock is accessible. Remove the two small bolts on the back of the handle. Then use a small chisel, screwdriver, and pliers to pry off the spring clip holding the rod to the latch. This clip must be mangled to get it off. Now the handle is free.

The lock is held by a sliding spring clip. A little WD-40 helps get it moving. The rod is held by a small metal retainer. With a small screwdriver, gently pry the retainer off the rod and the lock will be free.

With the glass removed I can get my hands into the area. I can also sand off the surface rust inside the door!

Now to remove the latches…

Kurt seeing you have the glass out I would recommend sticking a bit of sound deading material on the inside of the outer door skin.

I'm wishing and hoping that the PO used a HC piston.Lotus OEM pistons would have markings on the crown, like an arrow pointing toward the front of the engine, and A or B grade marks. I see no markings on your pistons. See the attachment for Lotus 9XX piston ID.

Forged JE Pistons that are sold by many Lotus specialists have a "JE" mark on the inside of the piston crown, on the exhaust side of the wrist pin boss. There's no arrow to indicate forward, so it's important to have the JE mark on the exhaust side of the wrist pin.
