that's pretty standard "water got into my oils" symptom.

im having trouble getting the head off now, all 10 head bolts are out, manifolds are off, thermostat off, and ive tried sticking a screw driver in the slots and all it got was a little bit of water seepage, and it got a few whacks with the rubber mallet but still not budging. any ideas?

A crowbar? or just leaver it

by **TOYROTA** » Wed Jan 10, 2007 4:27 pm

keep at it they are stubborn sumtimes.
or you could hit it harder

Just done the head on my old mans Surf.

We had to leaver it off with a crowbar. The locating pins were quiet tight.

OMG so shiny! · by **Dell'Orto** » Wed Jan 10, 2007 4:56 pm

Just spray a little CRC down the bolt holes, and give it a whack with the rubber mallet, it'll free up. Wouldnt recommend using a crowbar unless you're planning on machining it!

one of the head bolts has snapped off, it was rusty as, its about 5-6mm into the head from the block side, how can i get this out?

by **flygt4** » Wed Jan 10, 2007 5:40 pm

easy-outs?

by **Punter** » Wed Jan 10, 2007 5:46 pm

Is the head threaded??

You should be to pull the head off still.

OMG so shiny! · by **Dell'Orto** » Wed Jan 10, 2007 5:49 pm

Yeah just get the head off and use vicegrips to pull the broken one out.

by **Mike-** » Wed Jan 10, 2007 7:00 pm

so the head aint threaded? its sticking on something around there

by **andyztouring** » Wed Jan 10, 2007 7:48 pm

Use a block of wood and a LARGE hammer ,tap at bolts on side of head from underneath,can be stubborn to come off.

Rocker cover looks very similar to the forklift headgasket i've been doing at work over the last couple days

Most likely headgasket, an array of other possible things mind.

whats been going on here? there where shards of metal sticking out of both parts, doesnt look too good

by **andyztouring** » Wed Jan 10, 2007 10:00 pm

Most likely badly overheated and sitting with water in bore. Scrap engine and get another good one.

by **Mike-** » Wed Jan 10, 2007 10:04 pm

the engine ran sweet on the way home with a blown head gasket and didnt overheat, im not sure what happened before i got it tho. does everyone agree the engines rooted or will the 4k live another day?

by **andyztouring** » Wed Jan 10, 2007 10:14 pm

Looks like the bore is severely pitted ,only a rebore and oversize pistons will fix that engine.

by **Mike-** » Wed Jan 10, 2007 10:17 pm

pitted as in lots of little chunks out of it?

by **andyztouring** » Wed Jan 10, 2007 10:21 pm

The photo of the bore show pitting as big chunks out of it.Should be reasonably smooth with slight honing marks.Appears to be caused by sitting around with water in the bore .
