Toyota Lucida, Estima
Posted 06 March 2011 - 09:01 PM
I am a mechanic and have a few issues with a Lucida....
This is the first Lucida I have ever worked on, It had been off the road for around 2 years with a blown headgasket.
First of all I removed the cylinder head to find that right enough the head was shot, Been totally roasted, and there was water lying on top of the pistons which i knew wasn't good seeing as it had been there for 2 years. I atempted to turn the bottom end to try and get the pistons to move but they would not, I tried all sorts of thingd wd40, Jizer etc but had to go and get a rust remover and place it down the bores to get the pistons to move, I then moved the pistons honed the bores with the pistons in place the best I could as there was quite a bit of bore damamge due to the water sitting in them for a couple of years.
I then got a new head/valves and reconned injectors and fitted the head, The engine would not fire and compression was 0 on 1 and 4 and 80 on 2 and 3. on a wet test it was 150 on 1 and 4 and 200 on 2 and 3.
I removed the head again and removed the sump etc to get pistons out, Got new rings for it and refitted the head etc, Compression now is up to 250 on 1 and 4 and 300 on 2 and 3, its like it wants to fire but just wont and being an auto I cant even tow it to start it. I have also tried easystart to get it to go as well.
Any suggestions anyone kind of stuck now before I go ripping it apart again.

Have you ensured there is no air in the injector pump, I found it best to prime by removing the fuel return hose whilst priming furiously refit hose and make sure primer pump stiffens up. I also nipped the injector pipes one by one to ensure all air was out whilst cranking.
The other problem could be your pump timing being out by one tooth.
