while I'm putting my car back together I'm following these instructions from the turbo builders

FOR CORRECT TURBOCHARGER INSTALLATION


In order to avoid any possible damage while installing your turbocharger or premature operating problems, either of which could invalidate the warranty, please follow these instructions carefully and completely.

1. Check very carefully that there is not foreign material in either
the air intake or exhaust system, even the smallest fragments have
the potential to cause serious damage at the high operating speeds
of the modern turbocharger.

2. It is important that the turbocharger centre, turbine and compressor
housings are correctly orientated before final fitting. If the bolts,
lock tabs or V-bands are loosened to achieve this, check that all
mating flanges are correctly reseated and that all service manual
torque settings are adhered to when making final rigid connections.

3. All the relevant air, oil and exhaust gaskets should be replaced when
the turbocharger is fitted. It is important to use the correct new gaskets
in all cases, and never use sealing compounds at any turbocharger oil
connection.

4. The engine oil and filter should also be changed, using oil that
is specified for turbocharged engines.

5. Before connecting the turbocharger oil feed hose it is essential
to check for any restriction resulting from oil carbonisation, then
fill the oil inlet port to overflow with clean oil.

6. Crank the engine (without firing) until there is a steady flow of
oil from the drain port before connecting the oil drain hose.

7. Let the engine run at idle speed for a minimum of 3 minutes after
installation. This will prevent possible damage to the bearing system
due to oil delay, and have the effect of purging the system of any
residual contaminants.



Anyway, I'm at stage 6, how long should i have to crank the engine for to get the oil upto the turbo feed?

I have also fitted a new oil line with inline filter, and the sump was off the engine for a week or so, so its well drained, the oil has been refilled with new mobil 1, and I filled the oil filter with oil before replacing.

The car is still jacked up onstands at the front, would the car be better off level?

The battery didn't have loadsa life in it, but we flattened it trying to get oil upto the turbo.


Any hints or tips?

Should the oil light go out just off the starter motor?, I 've still got all the crank and phase sensors unplugged

nigel b

did you take the plugs out so it cranks quicker?
shouldnt take long to get oil coming out the oil feed pipe

studabear

tried it both ways, wondering if it to do with the filter? Think I better work back to the T piece on the back of the lock to start with

Yeah remove plugs to take strain off starter and allow faster cranking, then crank in 10 second bursts for maybe a minute.... if you have an oil pressure gauge you will see the pressure peek at around 80-90psi (on a stock pump), at this point you know oil is round the whole engine (or at least it should be! lol), if you really want you can pull the oil return hose off and see that it has oil passing through it then you know for 100% that the turbo is primed.
Refit plugs and fire up!

80-90 psi on an rs turbo! sureley that should be more like 8-9 psi lol

oil pump?

When I did it on a cosworth engine, took no more than 5 seconds of cranking to get oil to the turbo!

Defo doesn't seem right, its never had any oil pressure issues, it was fine when I took it off the rd, i've replaced the head gasket, sump gasket and it has a new hybrid turbo

oil was drained for about a week, while it sat with no sump on it, its now re filled to just over max, can't see why the oil pump would just stop working, although not impossible

I'm wondering if I could take the oil pressure relief valve out and back fill the pump with oil?

id pour some oil in the oil filler aswell to keep the cams wet if ur turning it over just in case the pump is fucked as we all know how cvh cams wear when they got oil

studabear

Sorted it now people, its running again, just need to re wire the twin fans, then trim the bumper to clear the intercooler and its good to go, I hope

what did you have to do in the end mate?

i dont get why people feel the need to take plugs out when turning a engine over. there is no way it can do any damage to the engine or starter motor.

Because it will turn over faster as there is no compression.

studabear

over filled the engine by a litre, still no joy so in the end filled the turbo to overflow, then fired the engine up, 2 seconds and the oil was flowing, then drained the excess oil off

little bram

yes mate but why the engine should still turn over fasteunf to get oil pressure unless the battery isnt charge.

because it would normally get the job done quicker, unless you have hiccups like the car in question.

There is no need to do it, I think it's just personal preference.
