Hi,I'm planning on rebuilding the above engine over the winter to hopefully install next year. I'm in no rush as the 1600 eg that's in now seems ok other than a couple of annoying oil leaks(minor). I've never rebuilt an engine and am definitely gonna need some guidance! Im planning on new rings,shells,valve guides,stem seals,crank seals all gaskets etc. The head is already off and bores look to be in good order but shiny a bit glazed. Before I start my first question is I take it I need to measure bore for right ring fitment. I hope all parts are easily obtainable. Thanks.
Not sure I can advise, but I do have an unwanted, scrap engine block (no head) off a digifant (I think) if you wanted something to practice on? Free if collected from near Abingdon, Oxfordshire.
Measure the bores in 6 places yes. I might have a thread here somewhere that shows where the measurements need to be.
Well I've took the plunge and took out Pistons carefully making sure all parts Caps are labelled to the corresponding bores.the Pistons look in very good condition. Bores are smooth odd light scratch present on one or two but hardly there tbh. Big end shells are very lightly scratched up with one exception on cylinder 4 Where the silver has worn to copper colour in the centre of shell approx 3mm. These will be replaced for new.crank big end journals are a lot better than I was Expecting and I'm hoping to change shells only without work on the crank is This doable.this is all a bit new to me so all advice is good advice I think.thanks.
Once the crank is out take the parts to your local machine shop or your bearing supplier and get them to measure the crank to check the size and you are within tolerances Regarding the bores you say they are smooth? But do they have any hone marks? Might be best to take this to the machine shop also and possible get it honed, then fit a set of new piston rings
Ok will look into that,bores are just shiny smooth with normal age related wear.if your referring to what I think People call "hatch marks"they are not visible.also a very tiny lip at top of bores I can barely feel it with my nail. I have no idea of cost,how much to hone block and do the crank do you think. Piston rings and shells don't seem to be much money unless I'm looking at sub standard stuff. 50 for a ring set & 30 big end shells 60 for a big gasket set including head bolts.
Sounds like it needs an hone My local machine shop charged me 40 for a hone last time Crank maybe ok but guide price 8 per journal to regrind and polish
I will post some journal pics for advice on the regrind and polish.as like you say may be OK as is. look good to me.
Measured big end journals standard book size says 47.80. Mine are coming up at 47.78 on all Four.so with .02 of wear am I right to just replace with new standard shells.journals are barely Marked.
