Engine by serial number0153019

right side second from the front

if you remove the engine mount then you must put a jack under the engine in safe area not to damage sump etc , to get old core plug out carefully drill a hole off centre of it and prise it out , clean and check hole surface , if ok then put sicaflex type glue on new core plug and hit home to same depth the old one came out !

The firing order is ( 1 - 3 - 7 - 2 - 6 - 5 - 4 - 8 )

The distributor rotor turns COUNTERCLOCKWISE

The marked # 1 position on the distrubutor cap faces to the REAR and slightly towards the drivers side

The engine cylinders / spark plug locations are numbered :

firewall

4 - 8

3 - 7

2 - 6

1 - 5

front

If someone has altered the disstributer, pull #1 plug, put finger over hole, turn engine over until compression on that cyl, line up timing marks (ball park only) and rotor will be pointing at the correct terminal for #1 cylinder plug wire connection, in the cap.

a haynes manual from a parts place will show you--or chec the condition of each plug wire-if one looks bad or falls apart--probly need to get all new wires /plugs

Before you removed the old unit did you mark the place as to where the rotor was pointing? if so just place it in the same pos. If not then you will have to look at the timing marks on the crank bring them up to cyl. #1 is up on top dead center and place the rotor rt. before plug wire contact on the dic. cap also make sure if dis. shaft drives oil pump that the two are installed rt. so that the oil pump will pump and not burn up the motor on start up or bind and break the keyway off the pump. you can use a flash light to look down dis. mounting hole to see how the oil pump keyway is sitting if it's not in the rt. place as to how the dis. will be place when setting it back to number 1 cyl. you can use a long flat blade screw driver to turn it into place to match up with dis. shaft....also if the timing maker are hard to see and you have a helper you can simply remove spark plug from number 1 cyl. and bump engine with starter (coil unhooked up) have helped put finger over plug hole when air forces finger out your on compression or close to top dead center .

drain tube located in engine bay, when looking into engine bay drain tube is just above right hand side chassis leg on bulkhead, repair for problem is locate lower casing inside passenger footwell then drill a hole in the centre of the lowest point then poke through with metal coat hanger, note when you drill water will drain in to vehicle collect and throw out then once you clear drain tube plug up hole, hole size required 5mm, lowest point round shape, good luck
