Any good machine shop will check the head for cracks before doing
any other work. See what they say.<br>

<div dir="auto">Approx 15k mi on rebuilt engine by PO.</div>
<div dir="auto">Recently detected water droplets and
creamy oil residue inside valve cover and near oil
filler.</div>
<div dir="auto">Pains as engine and car run so well ...
grr</div>
<div dir="auto">Did compression test and all OK at
around 150 psi</div>
<div dir="auto">Also had oil analysis done that
confirmed glycol in oil. Interesting no water found
... assume gets burnt off ?</div>
<div dir="auto">Upon reflection realise had been losing
some coolant. Have recently installed a recovery
reservoir and attributed the loss to air being
removed. Silly me.</div>
<div dir="auto">So need some ideas how to proceed and if
there is a likely culprit area that others may have
encountered ?</div>
<div dir="auto"> Maybe start by re torqueing the head ?</div>
<div dir="auto">Not sure how to retest though apart from
another oil test.</div>
<div dir="auto">Remove head ?</div>
