Wednesday: Complete second head and do parafin test

Thursday: Strip heads off car, transfer exhaust manifolds and heat shields to re-furbished heads.

Friday: Fit heads to car and start re-assembly

Your diary and time allocation reads similar to mine did as of a few weeks ago.

Hotel21....did you have to do a set of heads to/

Ok, good progress tonight.

Number one head is now fully cleaned and the valves lapped in ready for assembly....

Number two head is stripped, the colets, springs, spring base and tops all cleaned and the 6 exhaust valves cleaned. This head needs new inlets (they are slightly bent) so 6 inlets obtained from my old 3.0 heads and cleaned.

Tomorrow will be head number 1 build, head numerb 2 clean and lap valves in and build (assuming the head gasket kit turns up tomorrow!).

So, might be close to one day ahead of schedule.....so the tear down could start on Wednesday.

sounds good Mark   can i ask, the parrafin test, whats that? :-/

Its a simple way of checking the valves are all nicely seated.

You grind your valves in and re-assemble the heads as normal but, before fitting to the car, you fit some spark plugs (to basicaly plug the spark plug hole) and fill the combustion bowl with paraffin and leave it ......if the valves are well seated then all is good, if there not then you will see the paraffin leak through and into the ports.....a simple test which can save a future strip down!

Thanks Mark

Sounds like you are making good progress, Mark.  Keep it up, but watch not overdo it.   :-/

No, not done an engine recently but did have a heavy diary for a number of weeks prior to 14th November.

Then the big Head Diary Keeper decided that it was time to reassess the situation.

Now I take things a little easier and ensure that the candle is lit at one end only and with a flame size I can decide.....  

Take care matey....

I have done that in the past using petrol instead. What are the viscosity difference between parafin and petrol?

I thought parafin was a solid?  But I can tell you that petrol is lighter than water.

[hotel21]

Parrafin is (almost) the same as what is called Kerosene across the pond.  Basically the same as JetA1 as used in aviation, I think, but someone clever will correct.

You also get parrafin wax which is the solids removed from the refining process to get to parrafin, thats where you may be getting confusssssed a tad!

Ahh that common language dividing us again, Are you thinking of paraffin wax Theo?
Paraffin over here is the liquid I think you will know better as kerosene.
