Restoring TVR Vixen S3 RDO I 06J

[Hansoplast]

I have a (non original) good running engine in the Vixen.
But I am curious to my original 711 engine.
Head and valves look good but lot of carbonate.


But one piston marked badly. However nothing seen on the valves/head. Does anybody know what happened?



All bores nice without marks.
Crank turns (too???) easy by hand.
Will dismantle further to check the straightness of the rod under the damaged piston.

Wrong picture.
The badly make piston.

That's some damage. The dents at the bottom looks like marks left from a dropped valve but not with that head!!! Not sure on the round looking lumps can't realy see ? May be some one dropped a bolt in ??

Taken out all the pistons and found no further damage or excessive wear.
The pistons have blank sites and darker sides so were .... Have the bores checked for roundness.
Can anybody tell me by the picture what they think of it?




Damaged piston number 1 has no other bad points on rod, crank, bearings or cilinder.

Another question is what is the meaning of the numbers on the left hand front site of the block see pic. It says " 0F 19 ".
It looks as if it is a small plate with screws, but totally corroded.



Thanx for anybody's help.

They screw a number disc on to the block moulding buck and turn it to indicate the year month of casting ect so it's in the casting not rusted away. The blacking on the piston skirt could well be due to excessive piston blow by caused by a sticky ring etc.

Rebore + new pistons & rings.

Sorry

Cylinder head has had bigger valves fitted. Look like 41.3mm inlet and 34.9mm exhaust judging by the gap between the valves. Take the valves out and check for cracking of the ridge between the valve seats. Its common for them to crack here with those valves fitted.

I was.looking for prices of the parts needed.
Piston prices varies the most without indication for what reason. From 60 to 180 for 4 pistons.
Anybody a good advice. I do not need the most expensive ones.
I know the piston rings and oil scrapper must be right, but what is good?

Than cam followers are sometimes overlooked regarding quality.
Any suggestions on these?

With this info I will have a word with some engine firms about costs and material.

Still busy with the nose.
Strenghtening plate for the ... looked rusted also under the glasfiber so cutting them out, painting and reinstalling.
Another 6 hours gone.

After


Also reaping the hinges because of too many play. See elsewhere on the forum for info.


My Vixen with better and nicer detailing won't drive any faster.

Inspection hatch

Reading the article of changing the diff and the difficulty of getting him out I made an inspection hatch.
I made the panel in situ so it fits like a clove.
Cut out straight.


Made in situe.

Endresult

Fits like a glove

[prideaux]

well done

At last the car goes to the painter.
Hopefully the end of the "itchy" story of glass fiber everywhere.
Now the next biggest thing the color????

Taken the good results of the national Dutch football team I think Kings Blue will be a good choice.( instead of Orange)
