An interesting day today. It was one of those so close, yet so far moments when it came to seeing if it will drive.
The engine has been really rough on idle and we finally found out why today. After a lot of debugging with the help of E30Zone
– leading to leaks in the vacuum system being the most obvious issue it
turns out there is a giant leak between the break master cylinder and
the servo. After plugging with insulating tape the engine start running
normally and sounded great! Idle is still to high at 1000RPM but then
the donor had this problem before i took it to bits. Going to try
replacing a few vacuum hoses and see how it does. Also need to test the
AF
M, TPS and ICV (airflow meter, throttle position sensor and idle
control valve) electronics to make sure everything it working properly.
On to the second saga of the day! Brakes and clutch. Decided it was
time to fill the system and make sure the brakes work and the clutch.
Got one of those Ezybleed things you get use with tyre pressure. Very
good except none of the supplied caps would fit the marlin reservoir –
doh. Luckily with the help of a friend to hold the the cap in place it
sort of worked – still ended up with brake fluid everywhere!! First
thing some of the joints in the back started leaking so under the car
very quickly to bolt those up. The bleed nipples were a bit of a bugger
to open up, which became nice an easy after a trip to halfords for a
7mm ring spanner!
The big minus was the clutch master cylinder, this has completely seized up after bleeding the system. It wont depress at all so I’m going
to have to order a new one. May as well get the slave cylinder at the
same time.
If the clutch had of worked then I could have taken it for a quick run to the end of the drive way and back.
Petrol tank has a minor crack that needs fixing as well. I’ve found
some one who’s willing to give it a go, otherwise I’ve got some POR
tank sealer.u
