Question 3.2 JTS engine head removal?

Hi!

I had primary timing chain failure on my 3.2 159 and now i have 24 bent valves.. So it's a "head's off" job now.

Is it necessary to take the engine off or have you managed to remove the heads without removing the engine first?

Did it give any warning prior to letting go?

few times it warned with fault code P0016 and P0017. Before engine blew it also gave P0105 once...

Car was working as normally until the big bang... no weird noises or power loss. less than 60k miles driven car.

The engine will have to lifted fully out to do all three chains anyway, it could be worth looking at a new engine with the amount of work that needs to be done on yours.

If you consider a new engine look at eBay.au a brand new engine for the Alfa Brera 3.2 is £2,900 without shipping

No it's not. I did those chains already, engine was on it's own place all the time

I wanted to make sure if i have bent valves by doing compression test before i take off the heads and for that purpose i had to make timing gear first.

yes, that's right. done that.

I already took front head off also today.. Engine still on enginebay. So at least other one of those can be taken off without dropping engine.

Tomorrow i try to take rear one off also if i have time in the evening..

Did not have time until today to take the rear head off...

But now heads are on the table waiting to be dismantled so answer to my original question is: Yes, it is possible to take heads off without dropping the engine...

Story continues, head rebuilt with new stem seals, new valves and surfaces machined. Engine put back together with new head gaskets etc.

Engine does not still run, fault codes are now gone though.

has anyone of you experienced sticky hydraulic lifters on these? seems that valves could be a little open even when they should be closed... Without cams everything seemed ok.

Replying to myself again, it seems that hydraulic lifters can get stuck. Obviously with slightly bent valves they have reached their maximum working length and got stuck there. I pressed all the oil out of them in bench vice and now car is back up and running

How many hours of time did the job take you from start to finish? We're all the valves bent? Any piston damage?

all of them were bent but just slightly so there was no damage to pistons or valve guides.

It took several hours to repair this damage, hard to say exact amount because i worked on this in the evenings and whenever i had time... total could be somewhere 18-22 hours?

this was the most depressing part... parts all over the floor.
