It is easy to separate the engine from the automatic, easy than a manual for sure. The one thing you need to do is make 100% sure the torque converter does not separate from the tranny at any point in the removal and reinstall of the engine.
As for the TSII, I like to have a preinstalled grounded male 1/4" spade terminal so that if and when the TSII fails I can just plug the wire to the TSII sensor from the ECU into the spade and be back on the road. A spare TSII in the glove box is another way to go. |
Circling back to these sensors… i removed the fan shroud to replace all the seals behind it… and was treated to a great new view. One thing I found is that i have 2 of the thermo switches under the manifold. I guess the original went bad, and they just added a new one without removing the old one. The placement of the new one is what interferes w the dizzy adjustment bc it boinks the capacitor.
Anyway, I finally found the right spot and it’s running now. But that solved the mystery of ‘why cant i move my distributor like i need to.”  |

Thanks Wild …
Ive never separated an engine from an auto trans before .
Hopefully the Bentley man has some details.
Better yet, with better pressure and valve adj the noise will go away.
She’s leaking trns fluid too btw. Seems to be at the pan. Maybe from 2500 rpms in park? |

True.. I haven’t adjusted the valves yet, and havent even looked under the left valve cover yet. I guess i’ll do the adjustment, pushrod seals.. and the oil cooler seals before the next restart. hopefully the oil cooler seals job is not a bear.
might have to rebuild that alt too, or replace if available.
Meanwhile, the rust isn’t sleeping. ive sprayed WD40 on the exterior here and there to slow it down. Gonna need a lot of it for underneath.

it would be worth checking the status of your lifters now that you have ran it for a little bit.
You can run it without the alt belt on of course, if you want to eliminate that from the scenario for now. |

getting to the point, what happens if the TC does get separated? big spill? Trans ruined ? just curious. Glad to hear it's relatively easy to separate the engine from the automatic. |
Once the TC comes off the splines it is hard to get it back on and if the TC stays on the pump shaft you may well end up bending the pump shaft and engine removal may become much more complicated. If things aren't right when going back together you can also destroy the ATF pump on the front of the transaxle.

The alternator bearings should be quiet when the engine is running and with the belt removed you should be able to spin the alternator easily with your hands. |

Could be a tiny exhaust leak, pull the #3 plug wire from the cap as it idles, does the noise stop?

Got her running.. and actually runs pretty good. but, at low idle theres an irregular 'Ting Ting Ting' at #3. Sounds like a triangle from kindergarden music class. There's a bad oil leak from the cooler area. IDK if the noise is from low oil pressure / rod tapping cam? or if it's more serious. Hate to the remove fan housing off the bus for oil cooler service, if I'm just going to have to pull engine out anyway. So, leaning towards pulling the motor. (even tho there's a chance better pressure could resolve the Ting). Any idea what would cause that noise? runs smooth at higher rpm, and will almost idle. but that noise spooks me. Bus is on 15 degree down incline, and rear is lifted on jacks.. prob 25 degrees total. Maybe just starved of oil.. plus the leak.. lifter is failing?
getting to the point, what happens if the TC does get separated? big spill? Trans ruined ? just curious. Glad to hear it's relatively easy to separate the engine from the automatic.

| Yes wire the TC to the transmission. Also as you begin to separate the engine and tranny pry as necessary to get the TC clear of the flex plate. The guide on the TC is only 5/8" or so long so it doesn't take too much to separated the two, but if the pilot on TC is corroded in place it can take some force to separate the two. |

I don't know VW trans but with many be careful removing the engine from the trans, and use a strong wire or strap as soon as you have the clearance to keep the TC attached to the trans. Be sure to inspect the flex plate for cracks as soon as you can so if you have to source one it isn't at the last minute.

good to know. had hoped to get her running before winter to do some errands. looks like i wont make it. may pull the motor to the shed so i'll have something to do while it's cold out.
any trick to ensuring the converter stays on the transmission? just be aware and push it back, or it there a trick? |

The TTS Thermo-Time Switches are pretty dependable, it is the TSII head temperature senders that give the problems.
The main thing I would do to the TTS, is on the electric socket I would file the two retaining lugs for the mating plug to a slight angle to facilitate removal. Years ago, when I worked at a ski area, getting these engine to start in the cold was a common problem as they tended to run rich at altitude and thus didn't need as much cold enrichment. Trying to get the plug off the cold start valve was a royal PITA on a cold engine with cold fingers. FWIW, I file all the sockets on my L-jet engines this way as it saves a lot of cursing. |

Right below the distributor is the oil light switch.
The one with the brown connector is the TTS (thermal time switch).
Pull the three white wires and clean the connectors for the Injection system.
The TSII (temp. sensor two) causes most of the problems.
Good luck

does the plenum have to come off to replace the TSII ?
that's an odd looking gadget.. not clear on how it attaches or connects.
Mine's not running (after 7 year sitting) .. and since it causes problems it may be a prob on mine. |

hello tcash and thanks again for all your help...
You're welcome.
When taking off this electrical connection to the egr vacuum i find that the connection to the controller only has one contact.
Should have two contacts.
That is the blue connector.
EGR connector is black. Cold start valve is blue.
Could you advise would this cause an idle problem.
Find the black connector and connect that to the egr valve.
Connect the blue connector to the cold start vavle.

Good Luck

| hello tcash and thanks again for all your help... i am going a this in dinda of a shotgun type of way.. my latest is in reading the manual i see where to check egr and throttle you should pull electric from egr and run throttle in and out to see how egr reacts.... when taking off this electrical connection to the egr vacuum i find that the connection to the controller only has one contact that is the blue connector has one connector that is there and one that is non existant... there can be no connection between the throttle and egr... we do not have emmission controlls here and I am wondering if when whoever rebuilt the engine just deleted this from the plug...... would seem like ther could have just taken this off... but with vw you never know i am finding out... could you advise would this cause an idle problem and just how does the blue connector from the controller connect to the controller... can the large black rubber connectionbe rolled back from the blue connector... thanks for your help tim and sure appreciate your help. |

No worries. It is easier to follow along and see what repairs you have made if it is located in one thread.
If you have a different question. Change the subject title.
Maybe use this thread?

well being a new by or what ever and also not being computer r literate it looks like I made the over seers of this site unhappy...
when I look at this engine My jaw just goes slack as I mostly have no idea what I am doing... i have rebuilt an old willys pickup took it all apart and put it back to one piece and got it running and sold it. On the willys site you asked questions each time you ran into a problem. folks were pretty happy to help you out.
I thought it was pretty much the same here as I received a lot of good input. I do have the bentley manual and also the bosch fi manual and try to get things done by it before I post here.
as you can no doubt see from my posts I am just looking for answers...and am sure sorry that new threads are a problem with the administrator. I am just trying to narrow things down to help me with what I know almost nothing about... I sure do appreciate you folks for the past answers which have helped me muchly.... best to you in reply to the block and leave it on |
