2001 Porsche 996 LS1 Conversion Thread by 1dirtyZ

10 minute(s) of a 536 minute read

i worked on it abit more today , found a few oil line fittings loose ( forgot to tighten them) and i hooked up the oil pressure sensor . i also plugged the O2 sensor holes and fired it up again just to see if i got oil pressure ,,,, the good news is that the car sounded real good with the two holes plugged - just like a vette with an aftermarket exhaust , the bad news is the guage didn't register anything 

i took the valve cover off and checked and it was dry , so i started it it again and let it idle for a bit but still no oil to the rockers .

i'll try to get a decent external guage on the engine and see what it says , if still no oil pressure i'll drop the pan and try to stuff the pump with grease .

i guess this is to be expected when you run an external oil cooler and remote filter while using -10 hoses to connect them to the engine .

i also got the power steering pump pressure hose made , and i should have it as well as the pump in the car by next time .

well i took another swing at it : i got me a new guage , plumbed it where the porsche one was ( on the filter housing) and tryed again ,,,, no luck 

so i decided to take the pan off and see if the pickup tube oring was cut or not , and to pack some grease into the pump to help it prime. whell when i started taking the hoses off oil started coming out of them , which indicated there was some pressure. and when i dropped the pan i noticed there were some shavings ( very small) in the bottom ; this got me concerened as to where they came from , it didn't look like bearing material , so just to make sure i took number 7 rod cap off and looked , the bearing looked perfect , not a sigle scar on it. which leasd my to belive there was some pressure but not enough to register on the guage. and the oring looked perfect .

so i thought time to pack the oil pump , so i took the pick up tube off and started shoving grease into the pump . off course i did look inthere to see if there was any sign of damage to the teeth of the pump but could not tell from the angle i was looking at.

i then proceeded to bolt everything up and put 8 quarts of oil in and fired it up again , but still no pressure 

after bangining my head on the wall for a few minutes i remebered that i forget something ! i should have checked pickup tube clearance (pan to pickup strainer) before i bolted the pan on.

so now i'm stuck with no oil pressure but with a running engine ,,,, talk about a tease !

so the plan now is to figure this out in the most efficient manner , so first i compiled a lift of possible problem areas or issues that can lead to this , please feel free to add in what ever i missed :

- oil pan to strainer clerance 

- oil pump oring 

- oil pump not packed with grease to help prime it

- relife valve stuck on oil pump 

- bad oil pump lobes or teeth 

- pump did not seat well on block ( i used spacers on it to clear the double chain- which could also be the source of the shavings)

- barbell missing on back of block ( i'm starting to doubt myself)

- plug missing on front of block

so inorder to make this as painless as possible ( im really getting sick of removing and installing the balancer ) i'll be doing the following : ( see i'm using what i think i learned in collge here ! - process engineering and effeciency crap )

- drain the oil - again

- drop the pan and check for clearance using some clay 

- if clearance check ot ok , move on to the next step 

- remove the rear bumper and lines to gain access to the front of the engine 

- remove every thing from the front of the engine ( damn balancer, water pump , alt.)

- check that the plug is in there

- remove oil pump and inspect , and most likely replace it ( melling) wth an OEM 6.2 pump and pack the crap out of that one 

- put everything back in place 

- go do some good deeds; give to the poor , help old grannies cross the street , be pias (sp) for a few days and pray like there is no tommorow that i get some oil pressure 

- check for pressure again .

now if all that fails then i have a major issue , which means i have to drop both engine and trans to fix the barbell .

i'll be doing this probably within the next week or so , cause i have a race in bahrain coming up and the camaro needs some love 

forgot to mention that i finally got the power steering pump and lines in :0 so that gets scratched off the list !

01.11.11

well the small issue just got a bit bigger ,,,,,,

i dropped the pan again and checked for pickup tube to pan clearance and it came out to 1/4" which is pretty good . so i took the balancer out again , pulled the timing cover off and took ther pump off , i also checked it the spring was in there , and it was. so i swapped the oil pump with a factory unit that i packed with grease and bolted that in.

i filled it with oil again and fired it up again but no luck , still no pressure . 

onething i noticed is that when i dropped the pan the first time , i saw grease coming out of the hose going to the filter , so it did make it at least to the hose .

i also took out the filter and found grease in there but the hose going from the cooler to the pan had no oil in it .

so this leaves me with one last thing to check , which is the dumbell plug at the rear of the engine, which means i have to drop both trans and engine inorder to get to it.

but as i was heading home i thought of something, i was wondering if i can check to see if the dumbell is in there by removing the oil galley plug at the back of the engine ( kinda where the crank sensor would be but on the other side) and taking a peak . what do you guys think?

this is really pissing me off now , it is so annoying to know that you are almost there and then having to rip it appart.

01.14.11

well some goosd news to report : i swapped the oil lines going to the remote pump ans sure enough there was oil pressure but not content with that i had to make sure so i took the valve cover off and let it idle a bit while raising the idle a bit and a few seconds later i got some oil up there ! 

i got a vid of it ideling i just have to upload it and will post it soon .

i still have to take out the damn balancer again!! the car is leaking from the front main seal , so i have to loosen the cover bolts and and center it then put everything back again .

and funny how the human brain works ,,, you would think mine would be busy thinking about how to fix the oil pressure problem and other current issues ,,,, but not the rock between my ears i think i now know where and how to mount the twin turbos while still retaining the current mufflers ! but more on that later 

so lets see,,, next up is :

-fix the front main seal

-get a serp. belt on there,

-fix the ABS wire under the car 

-start routing the AC line

-bleed the brakes and clutch 

and as soon as i get the parts i ordered in i can :

-seal up the fuel sending unit and call the fuel system done 

-connect the heater hoses under the car to the pump 

-find a place to install the water temp sensor and wire it and call the cooling system done 

-install the tail lights 

-start messing with the rear bumper 

-finish the interior by installing the door panel, steering wheel, rear panel, and seats

-other assorted odds and ends

01.20.11

i guess i can scratch the clutch and brakes off the to do list ; i finished bleeding the clutch hydraulics as well as the brakes .

the front airdam came in so i slapped that on :

and then i decided to place the engine cover/ hood/ trunk or what ever you call it on the car and adjust it's latch. i thought now would be a good time to do so since i have to see how much room i have with the rear spoiler rams ( they take up some space and stick out quite a bit in the compartment) cause i should start working on the intake tube(s), any way here is how it looks on the car :

and i took the powersteering pump off again , this time i wanted to chage the way i had the pressure hose routed , the way its set up now is it makes a loop to connect both ends and i really didn't like how it looks , so i'll be redoing it in favor of a cleaner lookign setup ( more pics soon ).

and after some thinking ( that rarely happens ) i noticed that the only thing stopping me from starting the car and driving it is just filling the cooling system , but i don't want to do it twice so i'll just wait for the coolant temp sensor to show up as well as the heater hoses so i can plumb them all in and then call the coolat system done.

so untill those parts show up , i'll be doing:

- door panel 

- defrost panels

- A pillar cover

- front main seal

- new pressure hose for the power steering pump
