No breathers connected at all. I had not considered brake fluid but it is definitely engine oil. I have had a closer look in the plenum and there is a build up of engine oil on the engine side on the throttle butterfly valve (if thats what its called) and it is completely clean on the air filter sid...

I have started taking the engine apart to fit new piston rings and on removal of the intake manifold I have found plenty of blackish engine oil all over the inlet ports and even up the intake manifold. Is it possible for engine oil to get into the inlet ports and intake manifold as a result of the p...

Thanks for that, it does sounds similar as the oil rings in mine would almost fall down the bore when testing the gaps. I Just didn't know how tight they were suppose to be. Thanks again.

It looks like changing the piston rings is probably my best option. Does anyone have any recommendations on where to get rings or are OEM the best bet ? what are the tolerances if I were to get the pistons and bores measured? Would 4.0 pistons on 4.6 crank and rods give a compression ratio too high ...

I will see if I can find the old dipstick and tube but at the time I think it was compared using the tube as well. Is it possible for oil to make its way up to the inlet port from the cylinders ? The ports looked otherwise clean except for a small amount of what looks like engine oil sitting on top ...

Thanks for the quick replies. The breather pipe running from the drivers side rocker cover to the plenum appears to be clean at the plenum end but maybe a little oily at the rocker end. I have disconnected this pipe from the plenum/throttle body and it still seems to be smoking, but havent noticed a...

Heavy oil consumption

Hello, I was wondering if anyone might have any ideas as to why my engine has started burning large amounts of oil. The engine was built from a 4.0 block which I then put 4.6 pistons and crank into. The injection system is a 3.9 hotwire with a 4.6 "chip", the front cover etc is from a 3.5. I managed...

Hi everyone, I wonder if anyone would be to point me in the direction of a good high torque camshaft. The engine will be a 4.6 running on a hotwire EFI probably with a re-chip. This will be going into a series 3 lightweight land rover. Whilst torque is important I don’t want to limit the higher end ...

I checked all the rods and they are all in the correct place. I think its most likely due to the damage on the crankshaft to the sides of the bearing surface. Would a crankshaft regrind solve this problem ? Also the crankshaft has 4.5 stamped on it rather than 4.6 , is this a standard range rover cr...

hello, I have a question along the same lines that I wondered if anyone might be able to help with. A while ago I bought a 4.6 crank and some 4.6 pistons to go into my 4.0 block. but when i tried to fit them recently all was going well, the crankshaft was turning freely and the pistons went in fine ...

Thanks for the info. I currently have a 3.5 which has a 3.9 efi system on it, would it be possible to convert the 4.6 to distributor using 3.5 bits and then use the injection system. Would this restrict the engine in any way or hinder economy ? would the ecu need to be altered in any way? many thanks.

I have a 4.6 crank and pistons which I was contemplating using. the block has no markings on it except a plate which says its a genuine replacement part and there is no paint in ...
