What cylinder heads use the 058 block /

[b52400]

Was trying to convert a drive by wire head to drive by cable

[Believer]

058 blocks came with both large and small port heads. I don't know the swaps in and out but I believe the head does not matter. It's the throttle body, ecu, pedals. Vvt will probably need to be removed also. Others will know more.

Do you know if aeb is the only engine that is dbc

[b52400]

I have a aeb head that has a chip up neer the cam sprockets and I'm not sure if this will cause engine to jump timing I can't seem to find any aeb heads in my area so I was going to use a head that was dbw and swap intake manifold and use my drive by cable throttle body being that aeb is large port head

[Believer]

AEB is the only motor that used dbc in the B5s.

Do you have a picture of the chip?

You will be able to swap a small port head in no problem as long as you use the cam sprocket from your current head, swap the cam chain tensioner from your current head and of course the TB. Since the small port manifold doesn't have provisions to mount the dbc mechanism you would be correct using the large port.

Head doesnt matter.

You can swap throttle bodies, and even install the VVT tensioner in any 1.8t head.

Where is the chip? Does not seem it warrants a head replacement.

I'll see if I can take a good pic put its like one the cam journal cam still spins fine just don't want it to jump over and jump timing

Chip? Camshaft position sensor?



Same on all the 1.8t's

[b52400]

I mean like towards the back of the head were the timing marks are its right were you put the cap onto tighten the cam but the cap went on fine I might be over thinking it though

Regardless, nor need for a head replacement. Get a pic up and explain clearly with associated pics your issue, and we will try and give you the cheapest, best, and reliable solution. I see this fix costing anywhere from free to $50 tops.

[b52400]

OK how do I add pics?

Looks too close to the journal for me. I'd replace it but that's my opinion.

As for the crank position sensor, they are the same, true. The rotor for the sensor though is different between the two heads. So whichever head you switch to, if you do, use the rotor from your head.

AEB Impulse rotor - 078905234F

ATW and AWM impulse rotor - 06B905234A

ADR also was DBC 058 in other markets then the US. NA 1.8.

It's a hard decision

How would I timie the engine without the tool

I don't see any scoring on the cam. You'll be just fine. But I would make sure to locate the broken fragment and get it out, if you haven't already. Concern would have been losing oil pressure, but placement of the broken piece does not seem to pose a threat. If it isn't too much to ask can you possibly remove the intake cam to determine how bad it really is, to see if you will lose significant oil pressure. Pic necessary. Our car works on a closed loop oil pressure system. Pressure loss in one area can effect oil pressure in others.

As for timing, you need to have the cam cap installed. Arrow on each cam cap pointing to notch on each cam, 16 links on chain between cams, exhaust cam pulley notch lined with valve cover notch, and crank dampener notch lined to lower timing belt cover notch. With all these lined up, you have perfect internal moving assembly timing.

Yep it's out actually just put car back together and ran it runs just fine

Thanks for all the help I'll keep you guys posted tomorrow I'll be putting the cooling system back together and exhaust manifold will go back on but it seems that the timing is dead on and nothing has jumped so far.

That chip won't effect timing. It can effect oil pressure, though.

That was my primary concern when seeing the pictures, the effect on oil pressure and the general oiling of that journal.

[b52400]

Car just overheated !!! This is strange didn't bleed the cooling system yet to that will be my next move I might have reblown the head gasket

If it is a head gasket issue is it the head gasket it self the blows or the cylinder head will be damaged I'm sure I just slapped the head on and didn't correctly tourqe the studs in and sequence I'm sure thats were I failed but I'll bleed the system and take it from there

AJL is dbc also
