I'll need a thicker one than I used to get it out.. The wheels of the trolley jack pushed through the ply and I had to slide the whole lot out.. Sent from my SM-G900F using Tapatalk

when putting my type 4 back in I struggled to move my trolley jack across our rough tarmac driveway and did my back in
Heads re-guided And off to the shop for skimming and seat re-cutting.. what's the most he can take off the chamber before the outside needs taking down... or do I just go back to the shims that don't need to go in to make sure it seals on the right face.. Sent from my Hudl 2 using Tapatalk
Well that's coat no 2 ..The paint runs will give it that genuine oil leak look that latebay engines must have... Heads back from the machine shop tomorrow. .. what's the chance of having this engine back together again next week then!... Sent from my SM-G900F using Tapatalk
And the heads are back in town! Shiney Headshop in Warrington did the necessary chamber skim and valve seat cut ... Though he's not keen on VW's he's a good old bloke... New valves to back in then on we go...after ccing etc Sent from my Hudl 2 using Tapatalk
What's going on with the step in the ex guides ? Not seen them like that And on my phone both in and ex seats look same angle ?
Yeah exhaust guides definitely open up a little past where they pass the casting.. Not an illusion.. Was like that on the ones I pulled too. And yes just seat face cut.. Other two sloping faces are still dull but there.. Just.. Sent from my Hudl 2 using Tapatalk
Ah mine were just like the inlets ...old and the new ones ... i am right in thinking the inlets are 30 degrees and the ex 45 degrees tho ?
I don't know I can have a look tonight.. I left him a new set of valves to test em do they should match valve angle..... Sent from my SM-G900F using Tapatalk
Wouldn't have to worry about these things if I used some of our resident fixers.. I'm just too impatient to send things in the post and I drive past this place.. Sent from my SM-G900F using Tapatalk
No, both should be 30°, but if a proper job has been done, then it should have a 3 angle job on it... 30°, 45° & 60°
.....when I recut mine if was defo 30 degrees for the inlet and 45 for the exhaust ....I remember as I cut them 3 angled as well ...
Another problem with the stones and even the carbide cutter is that the shop you use may not be setup to cut the angles required. On a Type 4 head, VW specified 15/30/75 for the intake valve seat and 15/45/75 for the exhaust valve. You might end up with a 20/45/60 grind because those stones are more readily available for their tooling. The seat has to be cut to the prescribed angles and seat width and this process takes time: something the low budget shops cannot do and still charge you $200. Taken from ratwell
