Please help identify my engine. What is this oil pan?!
5 Attachment(s)
So, this is supposedly an S5 turbo engine. It's been rebuilt, but miles are completely unknown. It has been sitting for a few years. I oiled it up and spun it over, it had compression and then I lost pretty much all compression. Seals are stuck down. I've been feeding it MMO and I got some of the faces back, I'm going to throw it in the car and try to tow-start it.
Anyways, I bolt the engine up to my transmission, go to bolt up the motor mount bracket, and WTF is this, there's no spot to bolt it up and the oil pan is strange. Attachment 698597 Attachment 698598 Attachment 698599 Attachment 698600 Attachment 698601 You'll also notice the S4 N/A CPS. The front cover does have oil feed and return lines. What engine is this? I'm confused. |
Its a t2 engine set up for a first gen. Gsl-se oil pan and front cover. Cant really tell if its s4 or s5 from the pics, has an s4 water pump housing.
|
That water pump housing ain't S5 Turbo, the S5 turbo got three bolts and a groove for the thermostat o-ring (no gasket, just o-ring). Also the water-line to the turbo is not a separate nipple on mine.
|
hah, PO forgot to mention what car it was setup from...
1st gen GSL-SE or old school 13B all had those pans. need to see the driver side of the block to tell you more if it is an S5 or a S4. and wash your truck! |
Actually, RE, it is easy peasy. See the front iron? OMP? Two bolts. S5 got three.
EDIT: The signs I can see for it being S4 TII: -Water pump housing, that add-on nipple is not on the S5. Same with the top radiator/thermostat area. -CAS is S4 (though N/A) -OMP block-off plate is S4. |

not easy peasy, since it's not an FC front cover at all. ALL pre 1989 engines had a 2 bolt OMP. though read below.;)
the old school engines used the front cover to mount the engine, via those 4 bolt holes facing forward. FC front covers have 2 straight fins in their place. Attachment 698576 the exhaust port sleeves and from what i can tell the injector ports in the center iron are the only indicators of it being a later model 13B at all(but could still be a GSL-SE block but it doesn't look like it where the FC engine castings are a little more defined). but i can't discern if it has series 4 or 5 rotor housings by the pictures. the GSL-SE engines are almost identical with the exception of the rotor housings. |
Thanks guys.
Is it possible there is a 3rd omp bolt hole under the blockoff plate? I think it came with a non-mechanical omp somewhere... I'm hoping its an s5 engine with s4 waterpump housing and block off plate....ill get more pics tomorrow. And the whole truck is covered in bedliner. It never gets washed :) |

Anyways, why ISN'T there any more than two engine mounts on the FC? All other engines got it (S6++, piston engines etc). I think I remember that was one mod people did when putting S6 engines in the FC; putting the last mount on the firewall as the S6 (or something like that) |

all rotary engines got 2 engine mounts only. the location has progressed however. 1968-1985 the engines had 2 mounts similar to FC mounts located off the front of the engine. 1986-1991 FCs were mounted mid engine. 1993-2002 were mounted at the rear of the engine and the transmission used a torque brace to the snout of the differential to act as a transmission and front diff mount to keep drivetrain alignment even, the FD mounts are the largest so far and have stainless straps to prevent the mounts from ripping and to act as solid mounts under enough force. 2004-2011 RX8 progressed back forward though and were mounted mid engine up high. the latest were the most durable mounting systems. because time teaches us the mistakes of our ways. but it's just too difficult to adapt rear mounts to an FC with a torque brace system. the RX8 mounts however are liquid filled, when they fail they really fail. RX8 guys usually drain them at that point and fill them with silicone. |

I know there's supposed to be a rib under the oil filter, right? Sorry about the crappy pictures, I can get more.. http://i19.photobucket.com/albums/b1...7804642528.jpg Attachment 698537 Attachment 698538 Attachment 698539 |
I can't see a knock sensor? Meaning it is not a turbo engine? Or am I just not seeing it?
|
It's on the front rotor housing. That's an S5 T2 engine. (from the outside anyway)
|
Is a S5 S4 S3 franken motor.It has a 12a or 13b old school front cover,old school 13b oil pan SA 4 NA water pump and water pump housing!If is going back on a fc just swap oil pan and front cover.
|
yep, S5 TII block according to the rotor housings assuming it wasn't broken open and the rotors replaced with whatever. looks original though aside from the pan and cover.

Mystery solved! Thanks gentlemen! :)
I'm guessing any old S4/S5 oil pan and T2 front cover will work? And the megasquirt probably doesn't care which CAS is installed? |

and the S5 front cover puts the turbo oil drain in a different location than the S4 cover, due to the massive EOMP.

Okay! I got the oil pan off and another surprise!!
Atkins? baffle plate! Attachment 698127 Oil Pans and Related It looks like it's for the 79-85 13B... I'm going to need to swap to a FC pickup tube, obviously. Can I drill out the holes for the engine mount on this plate and still use it? |

can you have a look at those spark plug wires and tell me the date on them? i'd actually buy them.
|
the baffle plate won't work as it's configured for an early engine, the FC pickup tube would have to have a longer and larger hole cut in the center as well as the engine mount bolt holes. better off just selling it and buying the proper one if you really need/want it.
and yes, you're missing a tension bolt. |

and yes, you're missing a tension bolt. I'm missing the lowest tension bolts out of both sides. This engine is a god damned enigma. That's what I get for buying from a guy who bought it from a guy who bought it from a guy. |
your going to need an s5 water pump if using the s5 EOMP
.. and yes your missing at least one of the outer tension bolts .. looks like a rebuild then from that ,, and that is not a good sign that the previous builder had a clue |
PS,, the 13b sump baffle you have will never work with the FC front cover .. not only is it missing the engine mount holes and the cutout for the larger pickup.. you will find that the oldschool sump/timing cover is infact longer than the correct all FC combo ,, which just happens to be closer to 12a pan lenghts
