Cleaned out the EGR port through the head.............

Piston tops came out nice. The rest of the carbon will be removed with a kitchen teaspoon and then I will rotate the crank to bring each one up, remove carbon, and used compressed air to clean around the sides of the pistons on low pressure, but since I'm dropping the pan, I might just go ahead and re-ring it............

Tomorrow, I need to bring my cutting wheel to hack the darn exhaust downpipe bolts. The heads are totally rounded off and I will have better luck cutting, extracting, and re-installing. I will also swap out the 2 bad tires with a good pair I took off of my Metro. I still have to get those lifters apart and cleaned and clean up the intake valves. I am getting stainless steel exhaust valves from 3Tech and they should arrive shortly.

For now it's going to just get what's needed to get running right. After it starts paying us back, it will get a 3Tech economy cam and 10 degree gear. I have already replaced all 6 outside rear view mirror screws with longer ones so they stay put. Working on cleaning the interior and some exterior pieces now.

I had to work today, but I did get the manifold off the downpipe. The manifold is junk and luckily, I got one from Sam when I picked up the spare engine. I removed the o2 sensor and swapped it to the other manifold. I also removed all 4 wheels so I can swap and balance tires at work tomorrow. I did some more inspecting and found the rockers need some serious help and just like my Metro, the rear swaybar mount rotted off. The front control arm mounts will also require some immediate attention. They looked pretty good with only a couple holes, but when you start poking around...........

Anyway, here she sits tonight with her sister watching over her..............

Going to take some photos of a few rust issues tomorrow. Right now I have all my needed parts except the 3Tech stainless steel valves. Once I have those, I will have it running in no time.

Nice pics and explanations John. I see what they are doing with the groove. However. I have a real problem understanding #s. All I get is blah........ I could use some help understanding just what the results mean from that series of test.

have you given any thought to this procedure ?
this is as complete a set of test results as i could find - and they were done on a 10g engine

these test results show the procedure is beneficial. [/color]

I am also not sure how to put this quote into the box you are using when I read quotes from others?

Cleaned the rust scale from the rims after getting decent tires on it...........

Paint and tire shine............

"I am also not sure how to put this quote into the box you are using when I read quotes from others?"

look at the lower right hand corner of the post you wish to Quote
select the "Quote box"
3 grooves
... JM is entering new and uncharted territory ...
................................................................................
the test results show the grooved 10g engine has ;
uniformly lower exhaust gas temperatures.

and
less propensity to "ping"

the tests were run with 87 octane fuel .

there is another set of test results showing the relative pressure peak timing and duration with and without the grove
similar results .

the system needs a knock sensor feed back system in the ignition system to control optimize ignition timing

Thank you mwebb. Does it give you any more Horse power, or torque?
He JM it you missed a spot on those wheels. :lol

THE TEST RESULTS DO CLAIM TO REPORT
minor increases in efficiency , which should be translated to improved fuel economy .

i do not remember any increased horsepower or torque figures in those test results ,
"they" those performing the tests were having problems keeping the loads consistent for the purposes of testing at uniform low medium and high loads with and without the grooves
BUT
there are others who have used the procedure in small block Chevrolet engine who do report consistent improvements in the racing results as in less time to distance values .
search under "singh grooves"

"they" do not post actual test results as precisely and accurately as the test results linked though.
.........................................
if JM has not made the groves yet ..
i would suggest he make them as UNIFORMLY as he can by creating a template for placement and by keeping the depth and shape of cut uniform as well ....

i myself have zero experience with the procedure , but
i see some of the pressure timing peaks and pressure duration peaks and pressure amplitude peaks are erratic ..... at certain conditions

which may be variations per cylinder due to inconsistencies in the placement and depth of the singh grooves ,
or not , again i dunno , this is a SWAG based on the inventors comments....
but based on the proposed theory of how the procedure works it seems to me consistency would be a good thing in the application of the procedure

Well, my parts from 3Tech Performance arrived in record time...............

Posted Image

For the wife's ride, I got the 10 degree advanced timing gear and 3 stainless steel valves. I opted against the economy cam since she likes to drive at high RPM,s and is usually like any other woman, from the gas to the brake :)

I did not get the grooves cut yet because I am taking some advice you guys to use "precision" when cutting the grooves. I am going to make a template so the grooves are equal in all 3 cylinders. More updates soon!

Thanks Mike! I will PM you soon :deal

I opted against cutting the grooves in the head. I just wanted to get the car running and did not want any issues. I did learn a valuable lesson! Never re-use head bolts! I had no idea there would be any problems re-using them since I did on my 1998. So after torquing the used bolts here is what happened............

Posted Image

I spent a few hours with a small, sharp chisel and a hammer threading these 2 broken studs out, but luckily I did not have to drill! I had 2 new sets of head bolts to use. I have a set from 3Tech and another regular set. I forgot my 8MM, so I had to use the regular head bolts. I guess you get stupid after a few beers :)

Anyway, I got it all together and she fired right up! Just like on my Metro, I had to adjust the 3Tech cam gear since I was a tooth off to start with. I could hear it ping on load. After setting the gear properly, I was able to advance the ignition timing to max. Here is the engine all together............

Posted Image

While the engine was running, I let the coolant burp while I replaced the front pads and rotors. These brakes must have been original equipment! What a royal pain in the ass it was trying to get these brakes cleaned up and working properly again. I called the wife who was at work and told her the exciting news! She said...........

"Took you long enough."

If she only knew what I went through with the broken head bolts :smackface
Anyway, I figured a good test run would be the 20 minute ride to her work. I drove it up there and showed her the car. The car ran perfectly! She really liked the painted valve cover. I also had to get the official finishing touch on the windows...........

Posted Image

Now I have to repair the exhaust and then work on the body and frame. The new wheel covers made a huge difference also.

Paint is "Azurite Blue" and available from a local paint shop who is going to mix me up a couple spray bombs. I love the blue also!
